Lead developer · Mobile + Web · 2026A realtime multiplayer drawing game. For a social app, the product working is the growth loop, and it was crashing and desyncing mid-game, quietly bleeding reviews and the reason people came back.
What it was costing them
- It crashed as canvases filled up, the exact failure that tanks a social app's reviews and kills its loop. We re-architected the engine so it holds up under real use.
- Multiplayer desynced mid-game, breaking the one thing people came back for. We rebuilt the queue so shared canvases stay in sync.
- The feed served the same posts twice, dead weight on the surface that drives time in the app. We de-duped it.
