About me

Engineer by heart, a developer by trade. My goal as a programmer is to solve problems through software and help others learn to do the same.

Main Professional Experience

Freelance - Various Projects

December 2017 - Now

Various smaller projects as a freelance, mostly focused on the frontend side and Node. Working with various acquaintances, I've been able to collaborate on a number of different ideas, including -but not limited to- developing Node modules in C++, acting as Code reviewer and mentor for some teams, writing a small guide to learn programming Pensando en Programar (Thinking about Programming) and imparting some introductory courses to Frontend Architecture, as well as using some frameworks such as React.js, Vue.js, or Cycle.js and libraries like xstream.

Frontend Leader at idealista

August 2013 - October 2017

Development of critical features. Reconstruction of idealista's Frontend stack from an old Dojo 1.6 based mess to jQuery, Grunt/Gulp and LESS. Testing with Jasmine and Mocha. ES6, Lodash, Ramda, Backbone, Nightwatch.

We've gone through a lot here. These last years have meant not only a very visible redesign of the major parts of the site, but also a complete re-structuring of the frontend stack. Even the frontend team has been re-structured this year. We went from a completely unkempt Dojo codebase to a highly modularized JavaScript stack based on Grunt, LESS, lodash/fp, and jQuery, and introducing usage of tests both based on Mocha or Jasmine depending on the project. As of late, we're gradually pushing ES6 usage, and some other interesting libraries such as Ramda.

We manage our tasks through JIRA, following some Agile practices. Our code is managed through Git. I was personally responsible for some critical developments, such as the listing publication process or the shopping cart. I've also helped a bit developing a battery of Smoke tests using Nightwatch. As of the beginning of 2017 I'm in charge of the Frontend Architecture Department.
