Selected work

Three things I'm proud of

A Minecraft Bedrock toolkit in the browser: skins, capes, custom packs, and fifteen-plus creator tools.

What I did: designed, built, and run the whole thing solo, including the ad business behind it.

The full toolkit as a native desktop app, with overlays that work inside the game while you play.

What I did: ported the toolkit to a desktop shell, built the overlay system, and got it through a full QA pass and store submission.

Launching on Overwolf

Athlete progress tracking for a youth performance gym: sessions, lifts, streaks, and a team view of who's training today.

What I did: scoped it with the coach, designed the product, built it, and shipped it to the gym.

What you get when you hire me

I get a real version in front of real people fast, then improve it based on what they actually do, not what I guessed they'd do.

Design, code, deploy, analytics, and the business side. You talk to one person and that person built every part of it.

MC Tools runs as a business with thousands of daily players and ad revenue. I know what it takes to keep something running, not just launch it.

The short version

I'm seventeen and based in Seattle. I taught myself to code by building things people use instead of tutorial projects that sit on a hard drive.

When I'm not shipping, I play tennis competitively. Open to client work, collaborations, and conversations with people building interesting things.
