About this gig

Lead Unity/.NET engineer (10 yrs) who built an authoritative networking framework proven at 10 000+ CCU and shipped in 3 games with 1M+ downloads.


I craft low-latency real-time multiplayer state sync, rollback, anti-cheat, matchmaking and deliver fully documented prototypes, content-rich demos, or MVPs fast and ready to scale.

I specialize in multiplayer systems and complex game frameworks. My custom multiplayer framework is used in a game with 1M+ downloads — Trial Xtreme Freedom. I also build complete games solo, from backend to gameplay and UI. Here’s one of my most advanced projects: a multiplayer racing game with a built-in track editor and real-time co-creation: https://play.google.com/store/apps/details?id=com.lamiance.saturastate If you need robust multiplayer, custom editors, or scalable architecture — I can build it from scratch and make it production-ready.
