Product Designer at YouHodler, building a shared design system for two web products and shipping designs in code.

Germany

Message

At YouHodler, I head design for both web products alongside two designers and a developer. I built and maintain a cross-site design system, and designed and built youhodler.ar in React and Next.js.

I design regulated money products end to end, from onboarding and payments to trading, risk, and error states. I work with product, marketing, legal, and engineering, then take designs through prototyping and design QA before release.

At Course Center, I designed and built a Telegram-native course platform end to end; it reached 500+ monthly active users in three months, all acquired inside Telegram. At NEXA, I led design at a product studio and designed 10+ Telegram Mini Apps on a reusable foundation.
