Need a Unity developer to build your game, validate a prototype, or solve performance issues? I'm a Senior Unity Developer and Technical Lead with 10+ years of experience in software and game development, working across PC, Nintendo Switch, Android and iOS. I combine hands-on programming with game design and technical leadership experience. Whether you're starting from an idea or improving an existing project, I can help you build something playable, maintainable and performant. What I can help you with: Unity Game Development (C#): Gameplay mechanics, player controllers, game AI, UI, quest and narrative systems, save/load systems, and third-party integrations. Rapid Prototyping: Turning concepts into playable prototypes and vertical slices quickly, using Unity or browser technologies such as JavaScript and Three.js. Performance Optimization: Profiling, debugging and resolving CPU/GPU bottlenecks, rendering issues, draw calls and memory problems across PC, mobile and consoles. Codebase Audits & Technical Consulting: Reviewing existing Unity projects, identifying architectural issues, refactoring systems and improving maintainability. Technical Leadership & Developer Tools: Code reviews, technical planning, mentoring and custom Unity Editor tools to improve development workflows. AI-Assisted Development: Building and integrating workflows with Claude Code, Codex, AI agents and reusable tools to accelerate development while maintaining code quality. Some of my work: 🎮 Piece by Piece – Lead Programmer & Technical Director Designed core gameplay systems and architecture, led a team of up to five programmers and worked extensively on performance optimization. Improved Nintendo Switch performance from approximately 20–24 FPS to a stable 60 FPS. 🎮 Bogey Royale & Idle Pizza – Unity Developer / Technical Consultant Performed codebase and architecture reviews, then continued development of gameplay features and improvements for released mobile games. 🎮 The Polygon Loft – Lead Gameplay Programmer Built playable prototypes in under a week per iteration and led three programmers through development towards a vertical slice. 🛠️ Unity Asset Store & AI Developer Tools Created and published Event Manager and Localization Manager for Unity. More recently, developed AI-assisted engineering tools, specialised agents and multi-agent workflows for a custom game engine. How I work I focus on understanding what your project actually needs before overengineering a solution. I'm comfortable taking ownership of a feature, collaborating with an existing team, or helping define the technical approach from scratch. If you need an experienced developer who can write the code, understand the bigger picture and help your project move forward, send me a message and let's discuss what you're building.
