James C.

Senior Unity Developer

I’m a senior Unity and C# developer who builds games, prototypes, tools, and real-time 3D applications. If you're working with me, you're getting accountability, creativity and technical excellence. I use a cutting edge modern Unity workflow combining years of experience, the Unity MCP plugin and flagship models from Anthropic, Cursor and OpenAI. You're paying for a seasoned veteran using the most effective tools who can look at any line in your code and explain to you in plain english what it does and why it does it. What I can help with: Unity Apps / C# game development Gameplay systems, UI, tools, prototypes, production features, debugging, polish, optimization, and platform-specific fixes for PC, Android/iOS, WebGL and VR. AI-enabled games and interactive systems NPC dialogue, local model integration, procedural quests, AI-assisted content generation, narrative engines, runtime data pipelines, and practical AI features that fit inside an actual Unity project. Backend and service integration Databases, APIs, player/user data, analytics, multiplayer services, auth flows, admin tools, live content, and external hardware or device inputs. Technical rescue work I’m comfortable entering messy projects, finding the real problem, stabilizing the build, cleaning up broken systems, and giving the client a clear path forward. Recent work in 2025-2026 has included Mobile and PC strategy, action and MMORPGS, custom Unity tools, AI-powered narrative/gameplay systems, WebGL and VR projects, Android/iOS app updates, ad/IAP integrations, hardware-input arcade experiences, realtime Windows companion apps, and large-scale experimental game prototypes. If you’re serious about building something awesome, I’m happy to work hourly or by milestone depending on the shape of the project. Please get in touch!
