The multi-agent IDE for Roblox.

You describe a feature in plain English. A planner breaks it into steps, a scripter writes the Luau, and a reviewer checks it before it reaches your game. It runs as a desktop app and a web IDE, and stays synced with Roblox Studio live.

STORY

Money first.

I've always liked knowing exactly what I had. As a kid it was a piggy bank I counted more often than I spent from. Later it was small online businesses I started for fun, where I learned the part nobody tells you: a good idea doesn't make a business profitable, good allocation does. That's what pulled me toward finance.

I bet I can build that.

I saw a tool online and thought I could make my own. I didn't know how to code, so I asked an AI to help. The code was bad. The feeling wasn't. Talking to something that could reason back got me hooked on how these systems learn, think and talk.

A pitch to my dad.

When AI agents started doing real work on their own, I walked up to my dad with $300 of my own money and a pitch. He didn't know much about AI yet, but he listened and said yes. That Mac mini is where my real work started.

Why I started a chapter.

DECA isn't about memorizing definitions. It drops you into real business scenarios and makes you explain yourself under pressure. Whatever someone ends up doing, that skill carries. I want our chapter to be something members look back on as the place they learned to speak up.

Where I'm headed.

I want to build something of my own one day: an independent company, run on good judgment with money and good engineering. Until then, I'm learning both.

Lately I'm thinking about

How LLMs actually work, from the machine learning up to the parts that look a lot like neuroscience. They could change the world in days, for better or worse, and most people don't understand them yet.
