I’m a product designer blending creativity and functionality
New to Contra
KEI YAU is ready for their next project!
As UI designer for KeyPear, an enterprise-grade financial dashboard powered by blockchain, I visualized a clean, systematic interface to help businesses organize and manage their digital assets efficiently.
Adhering to the KeyPear brand identity, I designed intuitive dashboard layouts: asset overviews, real-time tracking, tokenized asset views, risk management panels, interoperability indicators, and secure credential integrations — all with a professional, trustworthy aesthetic that conveys reliability in the Web3 space.
The design emphasizes clarity for enterprise users, reducing complexity in digital asset management while reinforcing KeyPear's position as a forward-thinking platform bridging traditional finance and blockchain.

As co-founder and lead product designer of Wayy, I shaped a mobile app that makes meeting new people in Hong Kong feel safer, more natural, and actually enjoyable — moving away from the pressure and safety concerns of traditional 1:1 dating apps.
Wayy connects users into curated small groups for real-life hangouts (coffee chats, hikes, game nights, dinners), letting chemistry build organically with friends around for comfort and accountability. I owned the end-to-end product experience: from core matching logic: to intuitive onboarding, safety features, and joyful micro-interactions that keep users coming back.
Partnering closely with business and dev co-founders, we launched successfully on the App Store — hitting #11 in Lifestyle shortly after launch and now serving 1,000+ registered users across Hong Kong.
