From prototypes to product systems

Teatime Games

As Design Manager at Teatime Games, I worked on Trivia Royale, which reached No. 1 on the App Store, and explored new game concepts with the team.

My role

I managed the UI outside Trivia Royale’s game sessions: profiles, the AR inventory, topic search and category pages. I worked with developers to turn these interfaces into a consistent, reusable system.

Profiles, achievements and topics in use.

Helping the team keep pace

With up to two new quiz categories a week, the team needed a repeatable way to add content. I led a UI system of shared layouts and colour variables, giving each topic its own character without redesigning every page.

Testing an idea together

Diner Duo began as my idea for a cooperative diner game. I led the concept, art direction and design during an internal hackathon. Together, we built and playtested a working prototype to explore how face-to-face interaction could support cooperative play.
