    Python - Django developer

    Philippines - Tests: 2

    Linkedin: http://ph.linkedin.com/pub/elmer-medez/8/b08/83a Github: https://github.com/emedez Thank you for viewing my profile. I'm awful at selling myself, it gave me a headache just to write this text. I spent the last four years writing web applications using open source technologies. I suppose my forte is Python/Django since it is what I frequently use. I'm probably better than average but certainly not on the level of Guido van Rossum or Jacob Kaplan-Moss. I also have varying experiences in the following: Database: MySQL, PostgreSQL Frontend: HTML, CSS, Javascript, jQuery, Bootstrap, AngularJS Version Control: Git, Mercurial OS: Ubuntu, CentOS Deployment: Nginx, Ansible Editor: vim, PyCharm Others: Amazon Web Services, Vagrant, Test-Driven Development, Design Patterns, Refactoring ... and many more. My skill level on most of these are on the jack of all trades level, definitely not an expert. Those features that I use regularly are probably engraved in my muscle memory while the others need looking up on references. I have collections of best practices on these technologies which I had gathered from reading on stackoverflow, blogs and lurking on IRC channels whenever I'm not working (or not bonding with the wife and kid). I excel in Math during my studies and won competitions. This skill helped me a lot in solving programming challenges. I can dedicate 40 hours per week spread around 7:00p-2:00a UTC+8 daily (longer/more time on Saturday/Sunday).
