Multiplayer Game Backend & Netcode Engineering
Service description
I design and build the server side of online multiplayer games, so your players connect fast, stay in sync and never feel the seams. Over the past years I have shipped authoritative game servers, matchmaking pipelines and lobby systems for shooters, card games, io-style arenas and co-op titles across mobile, PC and console. My focus is netcode that survives real network conditions: packet loss, jitter, high latency and players who reconnect on the worst possible tick. I work with you from the first architecture sketch to a live, monitored cluster that scales with your concurrency.
A typical engagement starts with the transport and state model. I pick UDP with reliability layers or WebSockets depending on your genre, then build an authoritative simulation with server-side reconciliation, client prediction and lag compensation so cheating is hard and movement stays smooth. On top of that I wire matchmaking by skill, region and party, persistent lobbies with rejoin, leaderboards and seasonal ranking, and a session service that survives crashes. Everything is instrumented with metrics, tracing and load tests, so you know your tick rate and cost per concurrent player before launch, not after.
For infrastructure I containerize game servers, add an orchestrator that spins fleets up and down with demand, and put a thin, secure gateway in front for auth and anti-abuse. I can integrate your existing accounts, store and analytics, or stand up the whole stack from scratch. Deliverables come documented and load-tested, with a runbook your team can operate. If you already have a prototype that falls apart above a few hundred players, I also do focused rescue work: profiling, rewriting hot paths and fixing the sync bugs that only appear under real traffic.
— Authoritative servers, client prediction, reconciliation, lag compensation
— Matchmaking, parties, skill and region routing, persistent lobbies
— Leaderboards, seasons, sessions, anti-cheat and rate limiting
— Containerized fleets, autoscaling, load testing and observability
