Profiles and optimizes Unity game performance using Profiler, Frame Debugger, Memory Profiler; covers CPU/GPU bottlenecks, GC reduction, object pooling, batching, LOD, occlusion culling, and platform tweaks.
Profiles running Godot games using Summer MCP diagnostics, identifies hotspots in rendering/physics/scripting, and proposes targeted fixes with before/after metric tracking.
Profiles and optimizes Unity projects using player-build evidence rather than editor intuition. Helps diagnose frame time, GC, memory, and loading issues.

│ 120 FPS │ 8.3 ms │ Competitive games │
│ 144+ FPS │ 6.9 ms │ High-end PC │
└─────────────┴────────────┴─────────────────────────────────┘
FRAME TIME BREAKDOWN (16.6ms target):
┌─────────────────────────────────────────────────────────────┐

OPTIMIZATION WORKFLOW:
┌─────────────────────────────────────────────────────────────┐
│ 1. MEASURE: Profile before optimizing │
│ → Never guess, always profile │
│ │
│ 2. IDENTIFY: Find the bottleneck │
│ → CPU-bound: Frame time > GPU time │
│ → GPU-bound: GPU time > CPU time │
│ │
│ 3. ANALYZE: Drill into specific systems │
│ → Which function? Which shader? Which asset? │
│ │
│ 4. OPTIMIZE: Fix the actual bottleneck │
│ → One change at a time │
│ → Measure before/after │
│ │
│ 5. VERIFY: Confirm improvement │
│ → Check all platforms │
│ → Test edge cases │
│ │
│ 6. REPEAT: Move to next bottleneck │
└─────────────────────────────────────────────────────────────┘
