Sebastian A.

Ruby, Rails and C/C++ Lover


Medellin, Colombia


I am a programmer who likes smart solutions, and for this same reason when I coded up for web, I use rails and TDD-BDD methodology. I've been working for more than 7 years now with web technologies such as Ruby on Rails, Sinatra, Javascript/Ajax, jQuery, HTML5, MySQL, PostgreSQL, Heroku, Amazon AWS and others. I'm also interested to work with new trending languages such as Clojure and Erlang. I'm actively looking for new projects, so feel free to contact me.

    Need help configuring Curl on Linux/Debian
    Sebastian was very helpful during this project. He was unable to get access to my server because of my setup so he had to walk me through steps remotely. He was available in GChat the whole time making the process easy. He is good with communication as well. Thank you! Look forward to working with again.
