About me

The long version.

Most people pick a lane. I never saw the point.

I'm a Business Management senior at North Carolina A&T State University, and my resume reads like four different people. I've handled 600 packages a night at FedEx. I've run residential moves, restored properties, and turned wrenches on cars since before I could legally drive them. I've evaluated AI model outputs for accuracy and compliance. And somewhere in between all of that, I founded and shipped two live software products by myself.

No team. No outside funding. No computer science degree. I direct every product decision, write the legal policies, set the pricing, run the marketing, and build the actual software using AI assisted development. The business classes taught me how companies are supposed to run. The warehouse and the garage taught me how the work actually gets done: on time, under pressure, with your hands. My products are where all of that education shows.

Handshake paid me to score AI model outputs for accuracy and compliance, so I sit on both sides of this. I judge what models produce, and I ship products built on what they produce.

When I'm not building, I'm probably under a hood. Cars are my first love, and fixing them taught me the mindset I bring to everything: diagnose before you touch anything, respect the systems you didn't build, and don't call it done until it runs.

First love: anything with an engine.

What AI assisted development actually means

I decide the architecture and the AI writes to it.

I put a Lambda proxy between the app and the model so the client never holds a provider key. I built the three layer fallback so a provider outage degrades instead of breaking. I found the row level security hole in my own database and I closed it.

The model types faster than I do. It does not decide what gets built.
