About
Who I am
I'm a 14-year-old who loves programming and technology. I build web apps and write tech articles that beginners can follow.
I started web development in first grade of elementary school, and in 2023 I founded OgaTomo Systems, my sole proprietorship.
Today I work on system development and write for Tomoyan's Blog, among other projects.
I care about making expert topics clear for beginners — and I'll keep building useful things and sharing what I learn.
