Backend systems that have to be right in production, and lately the agents that help build them.
Five years of production .NET: service decomposition, event-driven integrations, and the SQL that has to survive Black Friday traffic on a franchise network. Currently at Linx, one of Brazil's largest retail-tech platforms, owning backend modules on an Azure-native microservices stack.
The newer habit is AI-augmented engineering: designing GitHub Copilot Agents and reusable Skills that take the repetitive, error-prone parts of the job off a team’s plate. This site runs on the same instinct: nothing here is a claim you have to take on trust when you could instead run it.

Outside the stack
Outside of work, the routine is more physical than technical. I train every day, and the running happens on trails, always without headphones: just the sound of the place, no playlist, no podcast, just footsteps and brush.
The rest of the free time splits between two habits that have nothing to do with backend work. One is testing and collecting niche perfumes, outside the obvious shopping-mall circuit: bottles bought, tested, kept, sometimes traded in as soon as a new one catches attention. The other is cooking recipes found at random on the internet, with no method beyond "looks good, let's try it": the result varies, but the attempt is constant.
Behind all of it is a slow-moving background goal, country by country: visiting all 195 countries in the world. So far 24 are crossed off the list, which leaves practically everything still to go, but that is the goal, no rush.
