About me
Hi, I'm Pedro, a Senior Frontend Engineer based in Porto, Portugal, with 6+ years of experience building high-performance, user-friendly web applications. I’ve helped scale BMW’s global OneShop e-commerce platform (25M+ monthly visits across 40+ markets), improving checkout performance and conversion, and shaped music promotion ecosystems at Oberon. I enjoy solving complex frontend problems with React, Next.js, TypeScript, and GraphQL, and I care deeply about reliability, performance, and clear collaboration. If you're looking to push the boundaries of web experiences, let's talk.
