I've worked in IT since 2010. I started in network operations at RNP's point of presence in Piauí, then moved to Correios, and I've been writing software since 2014. At the Piauí State Court of Justice I've built internal systems, led the administrative systems team and coordinated ICT infrastructure: servers, networks, the data center and the security around them. I've also worked remotely as a Rails engineer for US companies, on a telehealth platform and on a network management product.
Today I build web and mobile apps end to end, from the database down to the server they run on. AI is part of my everyday toolkit. I work with Claude Code, Codex, opencode and Cursor, write my own skills and agents, and use spec-driven development so that what the model builds stays tied to what was actually asked.
I care about simple, well-tested code, fast pages and infrastructure that doesn't wake anyone up at night.
