01The problem
Organisers couldn't collect fees inside the app.
They chased game fees through workarounds, and the business couldn't scale.
02The idea
Put the money inside the game.
03As shipped

The full flowCreate, pay, track, cash out.
04The hardest call
Designing for the messy moments.
Insufficient funds, failed transactions, retries: each one had to resolve without breaking the trust the rest of the flow worked hard to build.

05What I'd keep, and change
- 01
The messy moments are the product.Money only feels safe if every failure has a clear way back.
- 02
Get engineering in the room earlier.Validating technical constraints up front means edge cases get solved once, not redesigned twice.
The full case study is under NDA. Research, wireframes, interaction design and the design system: I'm happy to walk you through all of it.
