Hands-on Brazilian software engineer with many years of turning fuzzy business problems into systems that actually hold up in production. I have worked across the whole delivery lifecycle — architecture, backend, frontend, mobile, data modeling, CI/CD and the on-call pager that comes after.
These days most of my time goes into AI-agent platforms and distributed backends: Kubernetes workspace orchestration with agent runtimes, conversational-AI middleware routing millions of messages between chat providers and bots, and multi-tenant analysis platforms built on event-driven .NET and Node services.
I care about clean boundaries, tests that mean something, and code the next person can read. I also learn compulsively — a good chunk of my free time goes into simulations, low-level experiments and rebuilding things from scratch just to see how they work.

| 🌌 | universe-simulation | Gravitational N-body sandbox in three.js with an octree for force approximation. Protoplanetary discs, binary stars, black holes. | source |
| 🦊 | microverse-simulation | Predator–prey ecosystem on a 3D renderer written by hand. Six species, a six-gene genome where every gain is paid for. | source |
| 🐍 | top-snake | Multiplayer snake. Everyone who opens the page lands in the same arena, kept in sync over socket.io. | source |
| 🧬 | game-of-life | Conway's rules with three species competing on one grid — and then turning on each other. | source |
| ⚛️ | atomic-ionic-reactions | Ionic bonding simulated from the charge up, with Coulomb's law and real electron shells. | source |
| 🥁 | drum-pad-machine | A drum machine in a browser tab. Resizable pad grid, key bindings, BPM and a metronome. | source |
