Currently with Jaya Tech, embedded in the engineering team at Pipefy. B.Sc. in Computer Science from the University of São Paulo (USP).

The PDF below is always the latest release. It lives in a public repository, is written in Typst, and gets built by CI on every tag, so this link never goes stale.
