About Me
Law student turned developer. I study Law at a university in Tokyo while building real-world software at 42 Tokyo.
I leverage vibe coding with AI tools like Claude Code and Cursor to rapidly ship projects — from ETL pipelines and Discord bots to Chrome extensions and full-stack web apps. At 42 Tokyo, I write C from scratch to deepen my systems-level understanding.
Passionate about cybersecurity, I am a founding member of a security association at 42 Tokyo, compete in CTFs, and actively explore OSINT and binary analysis. TOEIC 925.
