WHAT I BUILD.

Mobile & desktop apps
Flutter apps for iOS and Android, and native macOS tools in Swift. Design, code, store release, and ongoing operations, all by one person.
Web & backend
Next.js sites and Supabase backends that power the accounts, content, and data behind the apps.
Japanese learning products
JLPT, keigo, and pitch-accent apps, plus a blog and YouTube channel for Japanese learners.

Every app here was built or updated with Claude Code, from planning through writing the code.
