My role
Full-stack engineer
Worked across both halves of the product. On the Next.js front end I built the character creator and character sheets, the in-game play screen, the new-game flow, account and achievements UI and shared components; on the Express/MongoDB API I wrote controllers, routes, models and middleware, including the achievements system.
