    Information Technology Consultant

    Uruguay - Last active: 11 days ago - Tests: 4

    My objective is to help people understand what technology can do for them. The past year I've been deep diving both Odoo (v8) and openerp (v7), doing extensive customizations on the base modules (especially the accounting related modules), plus developing a custom tailored application with over 2000+ total programming hours, serving as the lead programmer and technical analyst. I'm a top of the line programmer, with varied experience, ranging from web programming, server infrastructure and databases, up to openGL based games, scientific computing and machine learning. While I'm technically proficient, the main attribute that differentiates me from most programmers is that I dig deep when thinking about businesses, using my skills as leverage to help clients make more money.

    Experienced iPhone/Android Developer

    Vietnam - Last active: 1 day ago - Tests: 4 - Portfolio: 8

    Programming has been my passion before I become a professional programmer. When I was a student, I realized that knowledge from university was not enough for me to become a professional programmer. So I took some tests to become probationary student of a big software company. Gradually, I became an official employee of that company. Here, I could get lots of knowledge and experience. After that, I continue changing some companies as well as positions for learning and experience. So, although I have just graduated 2 years ago, I have about 5-year-experience. Now, I am confident of working for myself. My skills and experiences are following: Mobile Applications + iPhone/iPod/iPad, Android apps development + Web Service, Ajax, XML, JSON, RSS, SOAP, WSDL + MySQL, SQLite, HTML5, PHP, JSP, JAVA, Script, CSS + Facebook, Twitter, LinkedIn, Pinterest, Google Plus + Google Map Service, Foursquare + CoreData, CoreGraphics, Animation + Apple Push Notification + Socket programming Web applications + PHP + CakePHP Cloud computing + Google App Engine + Amazon web services
