About the developer
Yoshinya is built by one full-stack engineer with a front-end focus: seven-plus years of shipping products end to end with React, Next.js, TypeScript, and Node.js.
Currently a front-end engineer at a financial company in Sydney, Australia, building and maintaining the company website, its owned media, and LINE bots and mini apps. Yoshinya is a side project that turns the small hassles of that daily work into tools.
