At Gnosis, I designed Gnosis App, a self-custody wallet with card payments for 30,000+ users. I restructured wallet and payment flows, shipped a regulatory-compliant marketplace flow, and contributed to the app's 480-component design system.

I built interactive prototypes and microinteractions directly in the codebase with Claude Code, cutting implementation and handoff time by about 75%. I also built a custom animation tool that exports SVG, CSS and GSAP animations.

At KidsKonnect, I built a cross-platform design system with 790 components and 288 variables, and designed data-heavy childcare planning interfaces. At Noumena Financial, I co-built a tokenized design system with 1,000+ components and designed payment, invoicing and contract-creation flows.

At Froggly, I led three UX/UI designers and brought admin panels from five products into one shared design system. Across my product design work, I’ve designed fintech, SaaS, Web3 and mobile experiences, and tested and implemented features directly in code.
