Hi, I'm Mateus 👋

I’m a frontend-leaning full-stack engineer with 9+ years of experience, including 7+ years working with U.S. startups.

My strongest area is building product-heavy SaaS applications with React, Next.js, and TypeScript, especially where UX, performance, scalability, and product quality matter a lot. I care deeply about turning complex workflows into interfaces that feel clear, polished, and reliable.

Over the years, I’ve worked across health-tech, legal-tech, fintech, marketing websites, CMS-driven platforms, and workflow-heavy internal tools, often with high ownership from idea to production.

What I do best

  • Build modern web applications with React, Next.js, and TypeScript
  • Create scalable, reusable frontend architectures
