Message

At Blip, I optimized referral journeys across WebView experiences, contributing to an approximately 20% increase in referrals measured with Amplitude. I also developed and maintained Predicts in WebView and later React Native with TypeScript, focusing on a consistent, accessible experience for mobile users.

Previously at Feedzai, I worked on React accessibility and the shared design system, helped reduce frontend bundle size by approximately 20%, and contributed to a module-federation architecture. At Farfetch, I led an outsourced frontend team delivering a new in-store product, and at LOBA.cx and Ydeal.net I delivered websites and reusable frontend components.
