    "displayName": "Game Backend (Rust/Go + WebSocket + Redis + PostgreSQL)",
    "description": "A game server backend stack: Rust or Go provides the high-performance\nserver runtime for game state management and authoritative simulation,\nWebSocket connections maintain persistent bidirectional channels between\nclients and server for real-time gameplay, Redis serves as the in-memory\nstore for session state, matchmaking queues, and leaderboards, and\nPostgreSQL persists player profiles, inventories, and progression data.\n\nThe game loop runs server-side at a fixed tick rate, processing client\ninputs, updating world state, and broadcasting state deltas to connected\nplayers. Redis pub/sub distributes events across multiple server\ninstances for horizontal scaling. Message serialization uses Protocol\nBuffers or FlatBuffers for minimal bandwidth. This stack suits\nmultiplayer online games, turn-based strategy servers, and real-time\ncompetitive games. The main tradeoffs are tick-rate tuning for latency\nversus server cost, and the complexity of deterministic state\nsynchronization across unreliable network connections.\n",
