ABOUT
I've spent 8+ years building software, from founding my own agency to shipping products used by hundreds of thousands of people. I specialize in JavaScript across the stack: React for the frontend, Node.js for the backend, and everything in between.
What sets me apart is I think like a founder. I don't just write code, I understand product strategy, user needs, and business constraints. I can take a project from initial concept through architecture, development, and deployment.
Based in Porto, Portugal. Available for freelance projects and consulting work.
