C · Linux · IPCSystems

Concurrent Multi-Client State Synchronisation Editor

Built a C/Linux client-server backend that keeps shared document state correct across concurrent clients. Used signal-based handshakes, dedicated FIFO channels, versioned updates, optimistic concurrency control, and role-based write permissions to prevent stale writes, lost updates, and unsafe multi-user edits.
