Full-stack developer · Go, TypeScript, and whatever the problem asks for

I build small tools for problems I actually have: manga downloaders, a CHIP-8 emulator, a terminal pet that talks to my scripts, a declarative setup for my machines. Most of them exist because doing it by hand annoyed me one time too many.

Right now I'm writing a 2D physics engine in C++ and finding out what lives below the garbage collector.

Selected work

tama · Rust
Terminal tamagotchi that doubles as your assistant's face — a pixel-art pet that speaks messages sent by other programs. The cat above comes straight from its sprite data.

emugo-8 · Go
CHIP-8 emulator built on SDL2 — opcode decoding, display, timers and input.

rinha-backend-2026 · Go
Fraud detection with vector search. Third year running in the challenge.

workstation · Ansible
One YAML file sets up a whole machine on Arch, Debian or Fedora.

Stack

Go · TypeScript · Node · React / React Native · Rust · C++ · Lua
Postgres · SQLite · Docker · Linux · Ansible · Neovim

Blog · LinkedIn

Games, books, manga, and an unreasonable amount of time spent on dotfiles.
