Bert Li

I’m a Game Developer and Software Engineer with 3+ years of production game development experience building systems and features using Java and Python in multiplayer gaming environments. I specialize in Java backend development for game systems like server architecture, player state management, and distributed game logic that supports concurrent players.

I’ve also used Python for game development tools, data processing, and analytics—building automation scripts and data pipelines that support game operations. In my work, I design and implement game systems such as player progression, economy mechanics, and networking for real-time multiplayer gameplay, with a full stack game engineer understanding of both client gameplay and server backend needs.

At Roblox, I scaled player concurrency from 200 to 200,000+ during major updates while sustaining 100,000+ CCU for months, improving live-ops outcomes through backend optimization. I reduced server load by 30%, cut matchmaking latency by 25% with Redis-based session caching, and improved development velocity by 20% through Scrum adoption and refactoring into modular services—also designing and shipping large-scale systems like combat state machines, stat tracking, shops, wave progression, global data persistence, and event orchestration.
