About
Hi, I’m Tomaz Fernandes.
I’m a software engineer based in Rio de Janeiro, Brazil, with 10+ years of experience building backend and distributed systems.
I write about distributed systems: reliability, observability, messaging, and shipping small, reversible, production-safe changes. This site is where I publish technical notes, mental models, and occasional deep dives.
