Senior Full Stack Software Engineer · Open Source Contributor · Brazil
Software engineer from Brazil with more than 10 years of experience in full stack development, focused on backend systems, APIs and microservices. I build mostly with TypeScript, Node.js, Python and PHP, from service design and databases to React and Vue front ends. As an open source contributor, I fix bugs in projects from React, Google, Adobe, Apple, Netflix, Shopify, Uber and other organizations, usually in parsers, protocol handling, build tooling and web platform code.
30 merged pull requests to projects maintained by Google, Capital One, Adobe, React, Uber, Tailwind Labs, Valve, Shopify, Apple, Netflix and ByteDance Web Infra, plus the community project Portugol Webstudio.

fix: keep the default tolerance key when upper casing column names |

Both fixes were carried into maintainer pull requests so CI could run with repository secrets, and the merged commits credit me as co-author.

Community project. These pull requests are written in Portuguese, following the project's conventions.
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.
