About
I’m a Senior Product Designer delivering end-to-end UX and UI across web and mobile, with a strong focus on low-friction interactions and product outcomes. I lead design work from discovery to iteration, aligning interface decisions with business goals.
In my current role, I own UX/UI for 5+ mobile apps and help scale experiences to 1M+ users. By studying user behavior and analytics, I’ve lifted engagement 40% and cut churn 20%, while keeping every interaction simple.
I also build and maintain design systems and component libraries, reducing design-to-development handoff time by around 30%. I’ve delivered responsive, mobile-first interfaces across many projects while running user and competitor research to guide design decisions.
From onboarding rebuilds to early-stage product concepts, I’ve used usability testing and funnel analytics to reduce friction (like lowering key journey friction by ~25%) and improve onboarding performance. I enjoy close collaboration with product managers and engineers to solve complex product challenges end to end.
