The Server-Side Game Developer trek
Game server architecture, real-time networking with UDP/WebSockets, state synchronization, matchmaking, anti-cheat, scalability, and the infrastructure that runs multiplayer games at scale.
Networking fundamentals for games
UDP, TCP, socket programming, and why game networking is fundamentally different from web networking.
Game server architecture
Authoritative server model, tick loops, simulation determinism, and the architecture patterns for game server design.
Game protocol design
Designing the wire protocol for your game: reliable vs unreliable channels, message serialization, and bandwidth optimization.
Real-time communication — WebSockets & WebRTC
WebSockets for browser-based games, WebRTC for P2P and voice, and the infrastructure to support them.
State synchronization & prediction
Client-side prediction, server reconciliation, lag compensation, and the techniques that make multiplayer games feel responsive.
Matchmaking & lobby systems
Designing matchmaking systems, skill-based rating, lobby state management, and session creation.
Anti-cheat & security
Server-side validation, speed hack detection, memory tampering prevention, and building servers that cheaters can't win on.
Persistence & player data
Player profiles, inventory, progression, leaderboards, and the database architecture for game data at scale.
Game analytics pipeline
Tracking player behavior, funnel analysis for game designers, and the data infrastructure that improves live service games.
Scalability & infrastructure
Scaling game servers horizontally, global deployment, auto-scaling, and operating a live service at peak load.
Live service operations
Running a live game: deployment pipelines, hotfixes, incident response, and the operational discipline of a 24/7 service.
Capstone — ship a multiplayer game backend
Design, build, and operate a complete game server backend from matchmaking to analytics.
Trek complete. What's next?
You've walked the full roadmap. Now ship the capstone, write about it, and share the path with the next engineer who needs it.
