    Information Technology Consultant

    Uruguay - Last active: 3 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. Drop me a line at bfigaresvillalba@gmail.com if you want to discuss a project.

    First things what I'd like to say is that I work only on projects where you can provide me access to your resourses. For working "on blind", theory, suggestion or any other form of work where I can't see results... simply forget it, I won't work with you. Teamviewer is too slow for working, so only in some cases I'll accept to work on that way. My skills: Languages, envirements and projects C - POS terminals, Linux shared libraries, Cryptography, Protocols; Java - Cryptography, Protocols, JDBC, Ibatis; C# - Amazon MWS; Oracle PL/SQL developer; PostgreSQL + migration of projects from Oracle to PostgreSQL; Python - by need for scripts and help tools.
