What I'm looking for

I’m looking for a backend role where I can own scalable, secure real-time systems—building session orchestration, gameplay pipelines, and APIs that keep live multiplayer gameplay synchronized and dependable.

I’m a Backend Game Systems Engineer focused on building reliable, reusable gameplay infrastructure. At Async Casino, I engineered backend gameplay systems for 150+ slot game configurations in live production, and I architected a reusable feature pipeline covering 30+ modules like freespins, cascading reels, multipliers, pick games, and gamble flows.

I also build real-time session management with RTP-aware spin processing, balance handling, replay URL generation, and state reconstruction—plus admin and support APIs for gift spin management, game history, and replay access. In my projects, I delivered multiplayer systems like Geleg (200+ rooms, 500+ players in 14 days) and built end-to-end platform features like B2U’s Ollama/Qwen exam generation and Stripe escrow/payout routing, with an emphasis on secure APIs and synchronized live gameplay.
