Support Kohei Hishiyama (THINK DESIGN)

I’m Kohei — a freelance web developer and product creator based in Japan, operating under THINK DESIGN.

I build full-stack web products solo, powered by TypeScript, Next.js, Python/FastAPI, and AI APIs. Over the past year I’ve shipped 12+ independent products, each one a PoC-to-launch sprint.

Your support goes directly into building tools I believe in — not corporate roadmaps, just stuff that actually solves problems.
