Team
Six-person cross-functional team
Daberna is a live, synchronous multiplayer game in Tapsi’s ecosystem. I led a six-person cross-functional team, designed the game, implemented frontend work, and supervised backend delivery.
Operating constraints
The game had to keep a large number of connected players in sync during live episodes, while preserving fairness and allowing recovery from unreliable mobile connectivity.
Delivery
Real-time bidirectional communication over WebSockets.
State reconciliation and server-authoritative validation for synchronized play.
Redis-backed event distribution and Kubernetes deployment.
Reconnection and state replay paths for interrupted mobile sessions.
Scale
Daberna reached 400K peak WebSocket connections with sub-100ms p50 latency and 99.9% availability across approximately 110 live episodes over nine months.
