I'm a Senior Product Designer with 6+ years of experience designing complex, data-heavy products in fintech, infrastructure, and early-stage tech environments. I specialize in high-risk user flows where clarity, error prevention, and trust are critical, including products involving irreversible or financially sensitive actions. I’ve led end-to-end product design from concept to launch, built scalable design systems, significantly improved onboarding and early user activation, and influenced product and operational decisions that reduced costs and extended runway. I work closely with engineering and product leadership, often acting as the design authority on usability, risk, and scope tradeoffs. With a background in computer engineering and frontend development, I design with implementation in mind, understand technical constraints, and collaborate effectively with engineers to ship high-quality products under real business and delivery constraints.
