PortugalWhat I'm looking for
Frontend engineer with 11+ years of experience, focused on React and TypeScript. I've spent the last few years as the sole frontend engineer on a real-time forex trading platform — WebSocket-driven UI, streaming prices, candlestick charts, trade execution. Before that, a WebRTC video platform for healthcare. I work well independently, take full ownership of the frontend, and don't need hand-holding. Based in Lisbon, open to remote.
