What I'm looking for

I'm looking to shape complex digital products from discovery through launch, build scalable design systems, and partner closely with agile product and engineering teams on high-impact platforms.

I've spent 10+ years taking digital products from ambiguous early vision to market-ready experiences across fintech, B2B2C marketplaces, mobile gaming, and enterprise tools.

At Syncspert, I architected and scaled a company-wide Figma design system, reducing design-to-engineering handoff friction by 35%. I led research, user-flow architecture, and end-to-end product design across a complex B2B2C platform.

At Tweed, I owned mobile and web fintech UX, using 40+ usability tests, interviews, and analytics to shape onboarding and transactional journeys. At Lucky Lascar, I introduced A/B testing and usability programs that increased retention by 18% and in-game monetization by 15%.

Most recently, I've translated early business vision into roadmaps, prototypes, scalable component libraries, and cross-platform token architecture. I work closely with product and engineering teams to create practical systems that support high-velocity delivery without losing craft.
