“Initially hired David to review code for the game at a very early stage and was blown away by his abilities and after a round with the board we hired David as lead developer for the project. He brought with him other developers who also did great work and I can say with full confidence there would be no Domi Online without their expertise.”
Architecting a Scalable MMORPG in Unity
How we engineered server-authoritative networking, 64-bit infinite progression, and cost-optimised AWS infrastructure for a lean, investor-ready MMORPG vertical slice.

64-Bit “Infinite” Architecture
Bypassed standard Unity variable limitations with a custom 64-bit integer system for all player stats and experience tracking. Players can grind indefinitely without the game math breaking or overflowing, ensuring the “Harsh World” leaderboard remains competitive forever.
Cost-Optimised Cloud Infrastructure
Rejected the standard “auto-scale everything” AWS approach. Using FishNet networking, we built a lightweight server-authoritative backend that stripped unnecessary bandwidth overhead, drastically reducing monthly OpEx so the budget could be spent on content rather than server rental.
High-Density Environment Rendering
Implemented GPU Instancing for dense, interactive forests where every tree could be chopped. Engineered a system to swap static instanced meshes with interactive “Stump” prefabs only when interacted with, rendering 10,000+ trees with minimal draw calls on mid-range hardware.
Investor-Ready Vertical Slice
Delivered a polished, playable vertical slice demonstrating core gameplay, visual quality and technical architecture, built on the same foundation used in production.
Global Stress Tests
Successfully deployed and managed alpha tests with thousands of concurrent users across Asia and Europe, stabilising database timeouts through regional optimisation.
Lean Scaling
Delivered a massive open-world experience with a core team of just 3 full-stack developers, proving that efficient architecture beats brute-force headcount.
“David and Adam's workflow is always carried out with sophistication and passion, providing our team with vast expertise of the industry whilst maintaining a high standard of work and pride in each component fulfilled. Dedicated members who always goes above and beyond expectations to deliver. Great asset to any team!”
