About

I'm MJ (MJayNumberOne), founder of sparkinCreations.

What I Build

Software that respects users. No accounts required. No cloud dependency. No frameworks that break. No ads, no tracking.

Why I Build It

miniCycle exists because I needed it. I've used it daily for 200+ cycles. The engineering depth exists because I wanted to build something that lasts - software I can maintain for years without depending on someone else's roadmap.

The Craft

This is a showcase of what's possible with vanilla JavaScript and disciplined architecture. Every module uses dependency injection. Every feature has tests. Every decision is documented.

Music

I also produce original music.
