Ruby on Rails developer with 8 years experience, co-founded a startup a few years ago, now working in a small web development agency for the last 3 years.

I have been interested in Computer Science since I was a kid, when I started taking my first programming lessons. Later I took a degree in Computer Science and I have been learning and exploring new technologies by myself since then. During the last 8 years I have been focused on web development using Ruby on Rails as the main technology, although I have also worked with Node.JS and Angular extensively. During my career I have worked as a freelancer, co-founded a startup, worked for several companies and currently I am working in a web development agency called MarsBased.

I have been working with Ruby on Rails since Rails v2 in the development of several web applications, both as a freelancer, on a startup I co-founed and working for several companies. During this time I have also been learning both the language and the framework in-depth by reading, exploring its source code, practicing and following the industry leaders (like Railscasts in its time, RubyTapas, Shopify and Github).

Ruby has been my primary programming language during pretty much all my career. I have been using it primarily on a Ruby on Rails context, but also to write stand-alone scripts and other non-web related code. Since I started using the language I fell in love with it and have since then been practicing and learning more. I have read several books about Ruby (like the Pickaxe) and follow industry leaders (like RubyTapas).

I have been using Git every day as my only tool for version control management for all my career. I have used it both for personal projects and as part of a large team, using the git-flow methodology. I am familiar in working with branches, pull requests, rebasing, etc.

I have been using SQL in the day-to-day since college. I have mostly used PostgreSQL although I have also used MySQL in a few projects. Through the years I have gained a lot of practical experience, especially in performing complex queries.

I have been using Javascript in the day-to-day during my career as it's an important part of web-development projects. Although I have worked primarily in the back-end side of web applications, I have been in charge of building the front-end for some projects. Specifically, I have built some Angular single page applications. I have also worked a little bit with NodeJS. Even though I don't have a lot of experience with it I can find my way around. I am familiar with programming in an asychrnous way and making use of promises

I have been in charge of building a single page application using Angular in a few complex projects. I know how to create and structure an Angular app and I have had to build complex components to support non-trival UIs, making use of advanced Angualr features.
