about

$ cat about.md

I'm a full-stack developer based in Brazil. Right now I'm shipping public-sector tools at SEPLAM with Laravel and Postgres, after a couple of years building product front-ends in React and Svelte at Klever.

I care about small details, sharp typography, and code that's boring to maintain.
