03 / THE STACK

Solo, full-stack, shipping

Everything on this site — the Vite front-end, the Cloudflare Workers backend, KV storage, the desktop admin app and all 424 tool pages — is built and run by one person, end to end.

I am Mahin Mahi, a full-stack developer based in Seoul, South Korea, currently pursuing a BSc in Computer Science & Engineering. I build developer tools, ship client sites, and do security work — and I keep the tooling free so students learning the same things can use it.
