Get in Touch64-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-Optimized 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.
Funding Secured
The vertical slice developed by Ocean View Games was instrumental in securing $3M in seed investment.
Global Stress Tests
Successfully deployed and managed alpha tests with thousands of concurrent users across Asia and Europe, stabilizing database timeouts through regional optimization.
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.
Testimonial
“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.”
