Unity Multiplayer Developer
Synchronized, fair, low-latency multiplayer that holds up in production.
Multiplayer is where most Unity projects get stuck. I build networked gameplay across the Photon stack — Quantum, Fusion and PUN2 — including deterministic simulation, rollback, prediction and input buffering. I've shipped online fighting, brawler, racing and arcade games that stay fair and responsive across clients.
What you get
- Networked gameplay on Photon Quantum, Fusion or PUN2
- Deterministic simulation, rollback and client prediction
- Input buffering, lag compensation and desync debugging
- Matchmaking, lobbies and bot backfill
- Custom tooling to reproduce and fix online edge cases

FAQ
Common questions
Which networking solutions do you use?
The full Photon stack — Quantum and Fusion for deterministic, competitive gameplay, and PUN2 for lighter session-based multiplayer. I recommend the right one for your game rather than forcing a default.
Can you fix desyncs in an existing multiplayer game?
Yes. Reproducing and fixing desyncs is a core part of my work — I build custom debug tooling to capture the edge cases that only appear online, then isolate and resolve them.
What is deterministic netcode and do I need it?
Deterministic netcode runs an identical simulation on every client, which is essential for competitive, frame-precise games like fighters. For casual co-op, a lighter model like PUN2 is often the better fit.
