About
Software engineer with 4+ years across the full stack — C#/.NET and Angular on the enterprise side, Next.js and Supabase on the product side. For two years I led the IT section of a Brazilian Army battalion, responsible for every system the unit ran on.
Building and operating the same systems changed how I build them: hardened Linux hosts and Docker services, backups and monitoring that get checked, and documentation good enough that the next person doesn't need me.
