Maintained Figma libraries, variables and tokens; wrote implementation-ready specifications and Storybook documentation; reviewed frontend work against the design source. Used ChatGPT and Claude for research synthesis and documentation, and Codex and Claude Code for functional prototyping and design-to-code handoffs. Defined UX guidelines for AI-enabled experiences. Interviewed, onboarded and mentored designers within a six-person design team.
Improved an existing fintech product (Remote / Austin) through user flows, wireframes, prototypes and detailed UI, working with product and engineering to clarify interactions and implementation.
Hired, onboarded, managed and mentored a team of four designers across fintech product initiatives (Remote / California). Directed product strategy, research and UX/UI for merchant payment gateways, fraud management and virtual cards, using information architecture and behavioral analytics to inform decisions.
