I've spent 8+ years building web products — at health tech, fintech, and SaaS companies.

The best software isn't the most beautiful or complex. It's the kind that truly understands the people using it.

I'm a software engineer from Brazil with 8+ years of experience building production web applications for startups and scale-ups. I specialize in React and Next.js, with full-stack experience across TypeScript, Node.js, and Ruby on Rails.

I've shipped features across health tech (Moderna, Youper), fintech (BV Bank), insurtech (Boxx Insurance), and SaaS (PetScreening) — working both as an embedded engineer and through consulting contracts.
