Summary
🤩
Rockstar🎓
Top SchoolFabrízio De Royes Mello is a software engineer with 14+ years focused on making PostgreSQL-driven systems robust, performant, and scalable, currently contributing to Postgres upstream and extensions at PlanetScale. He combines hands-on backend and database-engineering experience—having worked on TimescaleDB core internals and the prest Postgres→REST project—with consultancy work helping teams design schemas, tune SQL, and orchestrate production instances. A long-time PostgreSQL volunteer and patch reviewer for the PGDG, he has authored and reviewed features that reduce locking, add IF NOT EXISTS support, and improve recovery behavior. His background spans both product engineering at time-series specialist TigerData and independent consultancy through Timbira, giving him breadth across architecture, implementation and operationalization. Based in Rio Grande do Sul, Brazil, he brings practical low-level debugging experience (memory context and catalog consistency fixes) that most application-focused engineers don’t usually have.
