Technical Lead
May 2012 - December 2014

Development of technologies to support the remote learning program, in partnership of the University and the Federal Health Care Ministry, to create an Open University for the Federal Health Care System (UNA-SUS).

With a very small team, we delivered improvements to the LMS, integration of a help desk solutions in the context of educational learning support, to extraction of metrics and reporting solutions to increase student engagement.

The most important solution we built, that was key for the success of the entire project, was an academic monograph editor, fully integrated with the LMS, the pedagogical plan and with custom, role based, review and approval system, generating at the end, a PDF in total compliance with Brazilian academic document formatting rules.

Full-Stack Developer (Freelancer)
January 2011 - January 2012

Complete code rewrite, as the code was old, unmaintainable, not localized, and codebase was originally written for Rails 1.1. Before this project started It had been upgraded to Rails 2.1 but lots of technical debts remained.

The portal was split into small applications with focused scopes, to better build a foundation for future scalability and help maintain lean codebase. A centralized authentication solution (based on CAS) was implemented to create a SSO solution.

Database was migrated from PostgreSQL, storing relational data and analytics, to a combination of MySQL server to hold relational data and MongoDB to hold analytics, resulting in a great speed gain with orders of magnitude (reports that took almost 30 hours to be generated in the past, are available in less than 10 minutes with the new infrastructure).
