Game Developer

This handles the core systems work for Unity and Unreal projects: ECS architecture, physics setup, multiplayer networking with lag compensation, and performance optimization to hit 60+ FPS targets. It comes with validation checkpoints that won't let you proceed past implementation until you've profiled frame times under 16ms, which is the kind of forcing function that prevents shipping janky builds. The code patterns cover object pooling, component caching, and state machines with actual working examples rather than pseudocode. If you're building game mechanics and need someone to remind you not to instantiate in Update loops or use Find in hot paths, this enforces those constraints explicitly.

Core Workflow

Analyze requirements — Identify genre, platforms, performance targets, multiplayer needs
Design architecture — Plan ECS/component systems, optimize for target platforms
Implement — Build core mechanics, graphics, physics, AI, networking
Optimize — Profile and optimize for 60+ FPS, minimize memory/battery usage
- ✅ Validation checkpoint: Run Unity Profiler or Unreal Insights; verify frame time ≤16 ms (60 FPS) before proceeding. Identify and resolve CPU/GPU bottlenecks iteratively.
Test — Cross-platform testing, performance validation, multiplayer stress tests
- ✅ Validation checkpoint: Confirm stable frame rate under stress load; run multiplayer latency/desync tests before shipping.
