ABOUT ME

profile picture

...Theoretical physicist meets Software-engineering.

I love to solve problems, whether they be working through a differential equation, proving a uniqueness math theorem, coding a nifty UI interface, or trying to mechanically stabilize that Lego structure I just built for my son, and enjoy the satisfaction and understanding that comes from reaching a clean, definite solution to an initially hard and challenging problem.

I value my ability to learn new techniques and methods much more than any “static” knowledge I may have gained (and forgotten) through time. While there is a certain level of technical knowledge that must be present to tackle any given problem, it is by researching existing solutions, coming up with new ideas, and thinking outside the box how most problems can be solved.

As a theoretical physicist I pride myself not so much in being able to understand complex problems, but in the logical tools I have acquired while doing so. These tools, such as logical consistency, being able to diagnose when a complex solution is right or wrong by looking at simpler edge cases, or mentally visualizing complex relationships, are the ones that carry onto other problems, such as choosing the right type structures to represent business logic results and potential errors, or using functional programming techniques for more decoupled and testable code.

For the past few years, I have moved from finishing my physics Ph.D. thesis in a very theoretical subject with arguably small “real-world” application, to non-stop working on a variety of web-related applications. I have founded and developed an ecommerce-like affiliate marketing website solely on my own, and later joined an exciting startup at tado°, where I developed frontend and backend solutions for their website and shop system. Nowadays I'm a lead engineer at AutoScout24, a bigger company where I'm helping to find solutions for problems affecting several teams, such as mobile/web development integration, and pushing frontend and backend code quality. During this journey, I've realized that I can develop tools and interfaces, learn new programming languages at a fast pace, and really believe I can tackle any problem, no matter its complexity, given enough time & resources.

I feel excited about the possibilities this new digital world brings through new forms of technology, and feel ready and confident to work in the next awesome project that pushes the envelope and finds new ground in one form or another. There's so much I want to learn, and so little time, I can't wait to get started!

Full-stack Developer 2013 - 2016

tado° Gmbh

Worked at tado.com, a Munich-based startup that does smart heating and cooling control through internet-connected hardware products. I was in charge of developing and maintaining the main website (both frontend and backend), the shop system along with a backend used by customer support to handle orders and shipments. In addition, I did the devops for the entire stack, from code deployments to server setup/upgrades, all in the cloud using Amazon Web Services. My core responsibilities included:

  • Frontend: Entire tado.com implementation based on Laravel 4 templating system, paying attention to page-loading performance, employing responsible design, and keeping an eye on cross-browser compatibility.
  • Frontend: Maintenance and upgrades to the tado.com webshop system based on AngularJS .
  • Backend/Frontend: Maintaining and upgrading a custom e-commerce system, both for the customer side API, and the company customer service agents frontend interface.
  • Backend: Writing most of the tado.com website backend, implementing advanced functionality such as a custom localization url/templating layer, website forms with Zendesk/Email notifications, automatic old link redirection, automatic Amazon cloudfront assets routing, automatic global/localized sitemap generation, and more.
  • Backend: Amazon AWS server & database deployments & configuration, including bash scripts for one-click deployment to multiple EC2 instances, automatic database backup / restore. This is in addition to the usual server LAMP stack configuration / maintenance .

During my work at tado°, I reached the following milestones:

  • Implementation of advanced code deployment strategies, such as blue-green deployments with zero-downtime using AWS Elastic Load Balancing API and docker containers.
  • Usage of bleeding-edge javascript on production code, such as Typescript's type system to improve code resilience.
  • Setting up a unified and performant logging infrastructure for all Website-related services by leveraging the Rsyslog-ElasticSearch-Kibana stack.
  • Creating a complete custom e-commerce system, including custom invoicing, emailing, reporting, automatic shipping (DHL API), payment processing (Payone API), in addition to order creation and fulfillment.
  • Implementing full MVC designs, both in PHP (through the Laravel framework) and in Javascript (through AngularJS and nodeJS Express framework).
  • Working with databases through an ORM framework (Eloquent), and also more directly but in a database-agnostic way through unified PDO interfaces (Laravel's fluent query builder) .
  • Learning and implementation of several programming design patterns, such as Event-driven architecture to better separate responsibilities between classes, the Repository pattern to separate database from business logic, dependency injection to keep classes modular, and the standard MVC pattern to structure applications.
  • Working and improving legacy systems, such as when moving from an older implementation of the website based on the Contao CMS system to the current custom Laravel 4 PHP-powered solution, including transitioning from a 3rd party shop system to a custom shop solution. Additionally, refactoring older code to make it testable, more decoupled and better documented.
  • Extensive use of the git versioning system (and it's github extension) to develop code that involves a team in structured way.
  • Writing unit-tests to improve code quality.
  • Writing clear code documentation, allowing the generation of documentation for the whole codebase automatically

Scala

Play Framework

View Details...
I've used the Play framework in AutoScout across several microservices, and have used most of it's functionality in one place or another. It's the default framework AutoScout24 uses for any new Scala microservice.

Functional Programming

View Details...
I always try to apply functional programming techniques to transform and manipulate data structures, such as Monad transformers, and also use Scala's powerful type system with things like Type Classes in practical cases such as JSON manipulation using Circe library. I've lots to learn in this area which can change / enhance the way one approaches coding.

RxScala

View Details...
I've used the Reactive Extensions for Scala in a few places, one being data aggregation in an API composition microservice in combination with Hyxtrix.

Sangria GraphQL

View Details...
I've developed two microservices that are GraphQL API backends using the awesome Sangria GraphQL library. It provides most things out of the box to do advanced things such as query complexity/cost analysis, authorization per field, and more.

Akka actors

View Details...
I've used actors directly in a project where the consumer of a Kafka topic needed to switch topics on the fly, the Akka actor orchestrating the switch between streams. In general, Akka actors are relatively complex (lots of ways they can be misused) and our team hasn't found a use-case that could not be solved using a more direct approach.

JavaScript

TypeScript

View Details...
I've used TypeScript since it was on version 1.4 for all my frontend development. This includes React applications, GraphQL frontend integration using Apollo client (awesome for having type-safe request/responses checked at compile time), and React Native development. The benefits that come from compile-time checks and the awesome type system that TypeScript provides give me no reason to choose plain JavaScript over TypeScript given the choice.

ReactJS

COMPLETE

NodeJS

COMPLETE

AngularJS

View Details...
I've used AngularJS only in it's 1.x version, and switched to React before the big version 2 rewrite came about. Haven't looked back since then since I prefer React's philosophy of JS-first vs Angular's HTML-first, plus I like to choose every single library that goes into my application instead of the "batteries-included" Angular approach.

Gulp / Grunt / Webpack

View Details...
COMPLETE

Testing

View Details...
Lately I've been doing all my testing using Jest (& enzyme), with it's awesome snapshot testing (which I recently found can also be used to do visual regression testing via screenshot generation using Chrome Pupeteer / WebpackDevServer plus a helper library). In the past I've used Mocha & Jasmine as well.

Server Administration

View Details...
I have four years of experience in deploying Web servers from scratch and maintaining them, and have successfully set up dedicated servers running LAMP for different CMS platforms, such as Joomla, WordPress and custom ones, under both CentOS and Ubuntu Server Linux systems.

I can also implement the most important security and performance best practices, such as OpenSSH public-key based authentication for syncying development and production servers, hardening of servers' security through addons such as the Suhosin Patch, CSF firewall, and applying the latest security patches routinely.

I have used cPanel, Webmin and the command line for administrative tasks, such as running diagnostics, viewing logs, configuring virtual hosts and setting up scheduled backups.

While working at tado°, I have deployed and configured servers on the cloud running multiple simultaneous Amazon EC2 instances behind load balancers.

Less

View Details...
COMPLETE (can use below as example) I've worked extensively with CSS level 2 and level 3 specifications while implementing fluid and responsive website templates, modules and interactive interfaces. I've also spent long hours and suffered my way through fixing cross-browser compatibilities issues (I'm looking at you IE!).

Being an “eye-candy” addict myself, I always like to try and play around with the latest bleeding-edge CSS3 features, both to spicy up designs and also to simplify code. I like CSS3 specially because most of the time its implementation results in both simpler code and better performance.

Due to the nature of browser compatibility, most designs that I've implemented that have advanced CSS3 rules also contain further jQuery javascript code for fallback compatibility for older browsers (w/ help of Modernizr.com), and a second fallback for javascript disabled browsers. This is in addition to the usual specific fixes required for the Internet Explorer family of browsers.

Since some time I've been using {less} as a CSS preprocessor, and twitter bootstrap 3 as a basic ruleset, which has greatly simplified the management of complex css stylesheets and reduced the amount of custom rules required.

Bootstrap

View Details...
COMPLETE

jQuery

View Details...
COMPLETE I have four years of experience using jQuery, and feel very confident implementing it into designs and applications. I've needed to use just about all of its functionality at one point or another.

From the Web app point of view, I've written basic plugins for form validation, implemented a clipboard with copy/paste functionality, used it to power a multitude of Ajax-driven interfaces, for event tracking under Google Analytics and more.

For design purposes, jQuery powers most of the designs I've implemented, providing animations & FX capabilities, allowing for interactive content, powering image & video galleries, providing performance enhancements like lazy image loading, and more.

Since the discovery of AngularJS, I've relegated my jQuery usage to simple tasks, using AngularJS instead when needing to write full-fledged client-side apps.

Other Software Skills

Bash

COMPLETE

Git versioning system

View Details...
Since 2013, I've been using (and loving) the git versioning system together with github.com to track code changes, collaborate with my coworkers when work needs to be divided, and prepare structured releases.

I've been using a workflow close to the gitflow one, with branches for every issue, and milestones to group issues that will go into a given release.

Physics

View Details...
After completing my bachelor degree with an inclination towards High-Energy theoretical physics, I moved on to my Ph.D. to work on topics related to Condensed Matter Physics, still from the theoretical point of view.

I've taken advanced classes such as General & Advanced Quantum Field Theory, Emergent States of Matter, Subatomic Physics and Statistical Mechanics, in addition to all the more standard introductory courses.

Math

View Details...
I've always been fascinated by the beauty of mathematics to describe complex imaginary structures, by how each mathematical theory builds upon the other like a set of infinite Legos, and how these “crazy” theoretical constructs come to play a role in describing the physical world. As such, through my studies I've taken more math courses than experimental physics ones (and enjoyed them infinitely more).

In addition to all the “standard” math topics such as Linear Algebra, Differential Equations and Complex Analysis, I've studied more advanced subjects such as Differential Geometry, Algebraic Geometry, Topology, Fiber Bundle Theory, Group Theory and Distribution Theory.

Statistics

View Details...
In addition to the regular statistic topics covered in the physics curriculum, I've taken a Probability course.

Development Skills

PHP

View Details...
I've used PHP extensively for the last 3 years for creating Web apps that run at the backend of TheCouponBay.com and tado.com, such as automatic image processing and cropping, custom content editors, automatic RSS feed & sitemap generation, API connectivity with Amazon, DHL, Payone, Pricegrabber, Google Adwords, Microsoft Bing, and more.

I've also worked with PHP for general data processing, such as transactions processing and cost balances, real-time graphs and histogram generation through MySql database querying, for templating website designs and for providing the backend of ajax-driven UIs. I'm also aware and have accounted for security issues such as user-session hijacking, XSS vulnerabilities and database injections.

Since 2013 I have worked with the Laravel 4 framework, which has allowed me to create robusts applications that leverage very good open source modules with the ability to add custom code on top.

I'm always looking for ways to improve my programming skills and stay up to date with the latest developments trends. Recently my obsession focus has been on unit testing, which I have applied through PHPUnit, and functional testing, which I have begun exploring using the Codeception framework.

Laravel PHP Framework

View Details...
I've been working with the Laravel 4 PHP framework for more than a year, which has provided me with a solid basis for implementing rigorous software practices, such as separating business logic from presentation, writing database-agnostic queries through abstract ORM layers, and widespread usage of an IoC container to implement dependency-injection.

I've been required to use most of the frameworks features to achieve different tasks, and I'm always looking for new ways to write older code based on new things I learn.

Javascript & AngularJS

View Details...
Although I've been using javascript since a long time through the jQuery library, since the beginning of 2014 I've been working on AngularJS applications, which has pushed me to study and understand javascript much more deeply than before.

In the development of AngularJS apps, among other things I've made use of javascript's prototype system, learned to deal with javascript imprecise float system, defined Model objects to represent database models which are absent from the angular framework, and recently I've been exploring the new functionality provided by the upcoming EcmaScript 6. If time allows, I'd like to learn Typescript, since I feel javascript's lack of type-hinting hurts it when writing complex applications.

I really like AngularJS 2-way data binding approach & testing capabilities, and consider it essential for developing complex client-side applications. I've started recently implementing unit-tests using the Jasmine library, and one of my short-term goals is to learn full e2e testing in addition to unit-testing for building rock-solid applications.

MySQL

View Details...
I've worked with MySql databases when creating Web apps to store and interact with data through PHP, and when implementing websites to both retrieve content and deal with additional information such as PHP sessions, user login information, marketing cookies, and more.

I am familiar and have used optimization best practices such as indexing, use of optimal field types and basic database tuning, plus implemented several MySql-specific math, date and sort functions for retrieving data more efficiently.

More recently, because of working with ORM frameworks, the necessity of writing direct sql queries has decreased, although the underlying understanding has help me perform optimizations and understand the inner-workings of the ORM framework better.

3rd party API integration

View Details...
While working at TheCouponBay.com, I worked on deeply integrating Google Adwords, Google Analytics, and Bing Ads through their API's. Because at Thecouponbay.com customers' transactions are not finalized onsite but occur at external partner websites, Google Adwords and Bing Ads own web interfaces are of no use when trying to determine keyword/ad performance, return of investment or conversion percentage, since they never receive the conversion data. This makes it a much harder problem to tackle than a regular ecommerce website, where transaction data is usually uploaded to these services at the order confirmation page through a javascript snippet.

The solution to this problem required the design of a common web user interface and database structure to handle both the Google Adwords and Bing Adcenter Ads marketing campaigns, allowing me to retrieve statistics, generate real-time graphs, modify bid costs, add new keywords, test creative performance and much more directly from a custom interface running on TheCouponBay.com's server.

The differences in architectures, the frequent changes in the APIs and the high volume of data processed made for a challenging and often times frustrating problem. For instance, in the case of Microsoft's Bing Ads API, no PHP client library existed at the time (unlike Google Adwords and Google Analytics), so a complete library had to be coded from scratch using native SOAP calls in order to request reports, modify bids, etc.

The Google Analytics API was used to link users to the transaction data, learn technical aspects such as browser used, screen resolution and geolocation, and additionally to measure website interaction and engagement through custom events tracking.

More recently at tado.com, I've implemented integration with the DHL DSI system to trigger shipments automatically from warehouses and follow up on their evolution, in addition to tracking inventory updates. I also worked on integrating Payone's payment API to process payments for tado.com's custom webshop.

I have worked with other APIs in order to accelerate productivity, automate data-processing and retrieve content efficiently:
  • Commission Junction & Linkshare APIs: Retrieval of commission payments and transaction data.
  • Amazon Product Advertising API: Retrieval and storage of product info, user reviews and listings from Amazon's product database.
  • PriceGrabber API: Pull product price comparison and lowest prices from PriceGrabber.com database.
  • HybridAuth API: This open source social sign on library was used to create a login system where users can use their social profiles such as Twitter, Facebook or Google+ to authenticate into TheCouponBay.com instead of needing to create a separate account (see in action).
  • Twitter API & Facebook API: Implemented automatic posting of content to TheCouponBay.com's Twitter and Facebook profiles, retrieving number of followers, and more.

Language Skills

English

View Details...
I started learning learning English when I was around 13 years old, a pretty late age compared to today's standards. However, after a couple of years I quickly caught up to a better pace after taking individual classes.

At the age of 17 I spent an entire year in Northern USA (Idaho), where I spoke English 100% of the time, which really pushed my English above and beyond anything I could have learned by living in a Spanish-speaking country only. After going back to Argentina, I successfully passed Cambridge's Proficiency English Examination (CPE), which is Cambridge's most advanced English examination (Level C2 of the Common European Framework of Reference) .

A few years later, I moved to the United States to pursue my Physics Ph.D. at the University of Illinois at Urbana-Champaign, where I lived for 6 years. Currently English is what I speak most of the time, since that is how I communicate with my German wife.

German

View Details...
I studied German and completed for four semesters of introductory German at the University of Illinois at Urbana-Champaign (courses German 101, 102, 103 and 104). After moving to Germany, I took 2 additional courses at the Goethe Institute.

Ironically, despite having three German children and a German wife, my progress in German has recently flattened, since I communicate with my kids in Spanish, with my wife in English, and with my German coworkers in English!

Spanish

View Details...
Spanish is my native language (although having been born in Argentina might make some Spanish purist say otherwise :) )

Design Skills

Photoshop

View Details...
My Photoshop abilities are rather basic, using it mostly for basic photo manipulation, plus the creation of basic logos, although I can follow tutorials to get around more complex effects or designs.

Adobe Lightroom

View Details...
My photography hobby has made me feel pretty comfortable using Lightroom, which I use extensively for manipulating my homemade photos. Sometimes it really amazes me how much a picture can change after some retouching, especially when using Lightroom's split-toning and white-balance modules to set the mood for a given picture.

Adobe Premiere Pro

View Details...
Used mostly for family video editing, I like to spice up my family videos by dumping them into Premiere's timeline and trying to leave only the bits that are enjoyable to watch. I use Red Giant's Magic Bullet suite for color grading and Neat Video for noise reduction, which together can produce some fantastic results when compared to the original film.
