    Information Technology Consultant, Odoo Expert

    Uruguay - 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, enterprise workflows, ERPs and databases, up to openGL based games, scientific computing and machine learning.
