AI Gameplay Systems
for Unity Games
Building intelligent gameplay systems, NPC AI, perception logic, and scalable gameplay architecture for modern Unity projects. Shipped code designed for memory safety, low overhead, and designer autonomy.
Robust Systems I Engineer
Gameplay systems built around clean separation of concerns, ScriptableObject-driven parameters, and event hooks, ensuring developers and designers alike can work rapidly.
Finite State Machine (FSM) Systems
Deterministic, scalable FSM architectures that govern core NPC loops, ensuring predictable, debuggable, and extensible behaviors for gameplay designers.
- Decoupled C# state classes
- Transition logic triggers
- Low-overhead execution

Production Process
How I collaborate with game studios to design, document, and deploy production-grade gameplay modules.
Technical Discovery
We analyze your game design documents (GDD), identify core mechanics, map NPC requirements, and plan the architecture for scalability.
Modular Prototyping
I build localized, interactive sandbox environments (labs) to prototype AI states, perception cones, and pathfinding before core integration.
Systems Integration
Injecting the structured AI modules into your main Unity project, hooking state handlers to animators, particle triggers, and combat controllers.
Performance Optimization
Profiling memory, eliminating garbage collection (GC) allocation in Update loops, using the C# Job System for raycasting, and tuning mobile frame-rates.
Technical Validation & Shipped Proof
Live playables and architectural breakdowns proving capability to ship high-performance code under real-world budgets and deadlines.
AI NPC Lab
Deterministic State & Perception Showcase
An advanced, interactive WebGL playground built to demonstrate production-ready C# AI architecture. Highlights real-time transitioning between Patrol, Chase, Search, and Attack states. Integrates customized hearing networks and physical vision cones using modern Unity rendering.
Bird Sort Mania
Scalable Logic & Dynamic Difficulty Solver
A commercially launched title featuring complex, highly-performant state checking, board solvers, and dynamic level creation logic. Optimized to process thousands of moves per second to manage game state validation and player hints on low-end iOS and Android devices.
Engineering-Focused Partnership
Unlike corporate digital agencies or generic generalist developers, I operate purely in the game engineering domain.
Production-First Mentality
No simple hack scripts. I write extensible, cleanly documented C# systems using design patterns that your existing game team can effortlessly inherit.
10+ Years & 100+ Games Shipped
Deep engine knowledge allows me to anticipate bottlenecks before they happen, designing memory-safe gameplay systems right from step one.
AI Workflow Acceleration
I harness custom-built AI tooling to rapidly scaffold architectures, allowing me to ship robust, feature-complete gameplay systems in weeks, not months.
Full Decoupled Architecture
All AI systems are architected with clean event callbacks (Observer Pattern), keeping technical designers and animators free to work without breaking code.
