Full stack by day, root user by night. I build platforms and automate infra with TypeScript, Rust and Java, and I've been living in Linux for 10+ years. Always curious, always breaking things (safely).
01About
Ten years of Linux, a soft spot for security and system hardening, and a habit of turning whatever I learn into something I can ship.
React, Next.js and TanStack on the front, Node.js and NestJS on the back, with Rust and Java when the job calls for them.
I created and maintain BrTools, the platform behind BrSuper Internet's ISP operations, from provisioning to monitoring.
Blog posts, configs and experiments, written down as I go. Some of them spiral into the rabbit hole.
02Writing
Notes, studies and thoughts on technology and beyond, from deep dives to quick notes I want to remember.

03Projects
Platforms, tools and experiments. Some run in production every day, others were built just to learn something new.
