I led end-to-end UX and visual design for multiple browser extension experiences, working closely with product and engineering to design patterns that were technically feasible, easy to maintain, and effective across different merchants and partner programs. I designed browser extensions that surface rewards and savings at the moment of purchase—operating within tight technical constraints while still delivering clarity, trust, and real value. This work required translating complex platform logic into lightweight, highly contextual experiences that feel seamless rather than intrusive.
