Ticketing and check-in platformfor events

The challenge

Event day is the worst possible time for a system to fail — the door queue cannot wait for a bug fix. The platform had to handle a surge of buyers in the minutes after tickets go on sale, and check-in had to work even when the venue’s WiFi is unreliable.

What we did

1. 01

   Built a ticketing platform that handles a sales surge without slowing down, with capacity enforced automatically — no overselling.

2. 02

   Designed a check-in app that works offline and syncs when connectivity returns, so the door never depends on the venue’s WiFi.

3. 03

   Added QR tickets that scan in seconds, with a clear view of checked-in vs expected for the door team.

4. 04

   Included a waitlist that promotes automatically when someone cancels, so empty seats are filled rather than wasted.

Outcome

Events run smoothly at the door. Tickets sell out without overselling, check-in takes seconds per person, and the organiser can see capacity in real time.
