Bruno F. Agency Contractor

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. 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 if you want to discuss a project.

Rails dev - Linux admin

Argentina - Tests: 19

Over the past 20 years I have been involved in several large projects including both software and hardware elements. I am looking to bring my expertise to businesses that have complex needs but don't have the volume to justify the expense of in-house talent. My skills include: - Project and team management: I have led web development projects from 3 to 30 people, using RUP, Scrum and homegrown methodologies. I know how to earn trust and gain the respect of collaborators, management, peers and clients. - Rails - I love the platform and have been working almost exclusively in RoR projects in the past 4 years for several different clients. - I prefer to use Thin, nginx, haml, jQuery, Semantic UI, Webistrano, MySQL or SQL Server, RVM and Rails 4.0 for new RoR projects. - I have experience consuming services like Twilio, SendGrid, UrbanAirship, and interfacing with payment gateways (usually Stripe and PayPal). - TCP/IP networking in general and the most popular protocols: HTTP/HTTPS, SMTP, POP3, SNMP, SSH. I also have a lot of experience troubleshooting connectivity and performance problems. I enjoy working with peers, but I can also work alone as developer and server administrator in small projects.
