// about-me

I design and build full-stack web apps end to end — from the first idea to deployment on Cloudflare's edge. I'm especially drawn to projects that turn complex information into something clear and genuinely useful.

Away from the keyboard, you'll find me into football and shogi.

Gitpawa Scouting Report

Turns any GitHub profile into a baseball-game-style player card. Stars, followers, languages and activity are mapped to six ability ratings (S–G), 44 special abilities and an overall score, then rendered as a shareable OG card. Card images are generated on Deno Deploy because Cloudflare Workers' 10 ms CPU limit cannot run satori.
