Hello World!
|Matheus| here!
I am a Full-Stack Developer that enjoys building things. I am currently based in Lisbon, Portugal.
Recently, I've revamped the landing page of Lexical, Meta's open source editor framework. Before that, I worked at GM Flow on AI automations, and built side projects like Rafael Witt, FolkYourself and jprac.
