About
Unity/C# gameplay engineer based in Portugal who shipped an AI-driven NPC narrative/quest system for a live mobile RPG, integrating Google Gemini via function-calling with strict JSON schemas to keep a deterministic game loop safe from hallucinations. Emphasizes high-performance engineering (zero per-frame GC, locked 60 FPS) with rigorous PR reviews and profiling gates, plus robust async/network patterns (UniTask, CancellationTokens) and LLM cost control via sliding-window context management. Seeking independent B2B contractor work at $45k–$50k USD/year.

Key Strengths
- End-to-end ownership of Unity gameplay systems from architecture through shipping
- Deterministic, secure LLM-to-gameplay integration using function calling + strict JSON schemas
- Eliminated unpredictable state-change errors (reported 100% reduction) via validation/firewall architecture
- Maintained locked 60 FPS with zero per-frame GC allocations through profiling, pooling, and allocation audits
- Strong PR/code review discipline with mandatory Unity Profiler/Memory Profiler gates
- Expert at identifying and removing hidden allocations (e.g., LINQ, class-based events) by refactoring to readonly struct payloads
- Robust async/network handling (UniTask + CancellationTokens) to mask latency and gracefully handle aborts/timeouts
- Cost/token optimization for LLMs via sliding-window context truncation (O(1) LinkedList approach)
- Cross-platform-ready input architecture via decoupled input providers
