About me

Software Engineering student at FIAP, building production-ready systems and automations. My core focus is back-end development with Java/Spring Boot and Node.js/TypeScript — and lately I've been expanding into full-stack with Next.js to ship complete products.

I'm also big on automation: using n8n and AI tooling to build smarter workflows and developer tools.
