Building cool shit at 15yo

Student, builder and open source contributor. I work where AI, developer tools and curiosity overlap.

01 / Method

Four steps to stay useful.

I learn by making things small enough to finish, then making the edges visible enough to improve.

01

Build

Turn an annoyance into a tool. Keep the interface close to the problem.

02

Test

Put the idea under pressure before calling it finished.

03

Learn

Read the failure, keep the signal and remove the unnecessary layer.

04

Repeat

Send the fix upstream and make the next version easier to build.

02 / Current orbit

What is taking up space.

A snapshot of the work behind the repositories. Not a résumé — a live state.

Shipping

Tools around AI coding agents, local-first workflows and better terminal feedback.

Active
Learning

How models behave when the interface gives them less room to be vague.

Ongoing
Looking for

People building serious things who want a curious intern in the room.

03 / Public catalog

Objects I have made.

A deliberately small selection from the public workbench. The full index has twelve public projects.

04 / Contribution ledger

Leave the code better.

The public trail: security fixes, edge cases, features and the occasional piece of documentation that should have existed already.

05 / Dispatch

A note from the workbench.

“We gotta be excited about the future. We gotta do things that make us want to live. It cannot be about problems every day.”

06 / Open channel

Say hello. Start there.

For code, AI, an interesting project or an internship conversation.
