I’m a Roblox game engineer with nearly seven years of experience. If you’ve ridden the rails in Build A Cart or hatched a stolen egg in Steal A Brainrot Egg, you’ve played something I worked on.

I built reusable agent skills for Luau development, debugging, and testing. They bring a project’s coding conventions and technical references into the task. I use Roblox Studio MCP to inspect and verify the implementation.

I built a Git integration for Roblox Studio with a Luau diff viewer. Object references survive a round trip through Git, and the plugin checks for conflicts before a pull can overwrite local edits.

@hayobayo

Great scripter, was able to bring all my ideas for my new game to life on time with great organization and coding skills. Wharkk made everything easy and neat to understand throughout his code and helped a lot when having to create my game in an extremely tight deadline.

@pinkalan

I'm extremely satisfied with the result, it turned out even better than I expected. He included clear, helpful comments throughout the code, which made it easy to understand, especially for beginner developers like myself. Overall, a 10/10 experience. I would absolutely work with him again.

Ale

@ale_.

He is the best scripter you can find, does his work quickly, and makes all the necessary revisions and fixes. Plus, he explains everything and gives you all the step-by-step details on how to add or configure the system. If you're going to hire a scripter, he's the one.
