Senior Full Stack Software Engineer · Open Source Contributor · Brazil
Software engineer with more than 10 years of experience in full stack development, focused on backend systems, APIs and microservices. I work mostly with TypeScript, Node.js, Python and PHP.
In open source I fix bugs in parsers, protocol handling, build tooling and web platform code. Every pull request starts from a failing test and explains the root cause.

JSX-style rendering directly inside plain HTML. No compiler. No transform. No build step.
Voodoo.js reads the markup the browser has already parsed, recovers each JSX expression and runs it through its own lexer, Pratt parser and AST interpreter. There is no eval and no new Function, so it works under a strict Content Security Policy, and every region is a reactive effect that re-renders when its data changes.
