01
The operational problem
Concurrent and offline editing require more than live transport: changes must merge deterministically, survive interruption, replay safely, and remain recoverable over time.
COLLABORATION INFRASTRUCTURE
A native and server-side synchronization engine coordinates collaborative editing through semantic commands, deterministic state, reconnect behavior, and recovery.
Evidence statusImplemented system
02
The system response
We developed the collaboration engine across native Swift, a Rust CRDT layer, authenticated WebSockets, and durable PostgreSQL persistence.
03
Operational impact
The workspace supports synchronized editing, history, migration, reconnect, and recovery through one coherent architecture.
