    Expert programmer with a math background

    Colombia - Last active: 1 day ago - Tests: 8 - Portfolio: 6

    I'm a programmer (though really a mathematician) with over 10 years of experience developing web & desktop apps. I've been using Python frameworks (like TurboGears2, Flask or Django) for web development for a long time, but I'm also very capable of working on a more traditional stack using WordPress, Drupal or CodeIgniter. I can do frontend development also using HTML/CSS and I'm particularly fond of jQuery for AJAX behavior and in-browser animation. For non-web development I use a lot of Python for scripting and rapid programming and Cairo/GTK+ to build graphical interfaces that are portable between platforms. I'm particularly interested in scientific and math-related software but I can do other kinds of programming. In short: I want to build things I can be proud of.
