Hi, I'm James, a multi-platform game developer skilled in Unity, Roblox, FiveM, and Minecraft.
In Unity I build PC, console, and mobile games with C#; in Roblox I script combat, RPG, and tycoon systems with Lua; for FiveM I develop custom GTA V scripts on ESX and QBCore; and for Minecraft I create plugins, mods, and complete modpacks for Java and Bedrock. I cover the full pipeline: gameplay mechanics, UI/UX, multiplayer, server setup, debugging, and optimization. Whatever platform you choose, expect clean code, fast turnaround, and clear communication.
Let's discuss your project today!

FAQ
Can you build the map and 3D models too, or only script?
I can do both. I'll build the assets, or you send me pre-made models and I'll script them — whichever you prefer.
Can you make the GUI/UI as well?
Yes, full GUI and HUD design and scripting. If you already have your own UI, I'll script it to work.
Can you build a complete game from scratch?
Yes. Message me with your concept, current progress, budget and deadline, and I'll send a custom offer with an exact timeline.
Will your system work with my existing game?
Yes. Share your place file or game structure first so I can integrate it cleanly without breaking what you already have.
Do your scripts cause lag?
No. Every script is optimized and profiled, including on the cheapest package. Server-side validation means no exploit-driven slowdowns either.
Can you fix a bug in my game?
Yes. Send me a clear description of the bug plus a Team Create invite or the place file, and I'll diagnose it before you order.

Ongoing collaborationSecond time hiring him and he's just as good on the repeat. Found what was breaking my shop almost immediately, but what I appreciate more is how he works, he doesn't just fix the symptom and disappear, he leaves things better than he found them and makes sure you understand what changed.

Ongoing collaborationMy experience with James is genuinely one of the best experiences I've had hiring anyone. My coins weren't saving and I assumed it was one bug, he found three stacked on top of each other and explained every single one in plain English so I actually understand my own game now. He also caught a duplicate...
