ABOUT

I'm a senior frontend engineer with nearly 14 years of experience building accessible, high-performance web and mobile apps with React, TypeScript and Next.js. I bring a product mindset, caring as much about what to build as how to build it. Right now I'm at The Plant, developing core features for the delivery platform of a global quick-service restaurant brand, working remotely from Porto, Portugal. Before that, I spent six years at Baopals leading a front-end team and helping shape the product. AI is central to how I work. I use Claude Code every day to plan, build and refactor faster, and I'm currently learning AI agent development with the Vercel AI SDK and MCP. Outside of work I'm a yogi at heart, keeping balanced with yoga and fitness while code keeps me curious.
