Currently I help people and teams to take the full potential of relational databases, especially PostgreSQL, helping teams to design the structure of the database (modeling), build physical architecture (database schema), programming (procedural languages​​), SQL (usage, tuning, best practices), optimization and orchestration of instances in production too. I perform a volunteer work for Brazilian Community of PostgreSQL, supporting mailing lists, organizing events and some admin tasks. And also I help a little the PostgreSQL Global Development Group (PGDG) in the implementation of some features and review of patches.
