Selected Projects
Curated, not recent — four things worth explaining.
01 AI Engineer OS Engineering
02 100 Day Engineer Challenge Learning A file protocol and supervisor loop that lets a coding agent work unattended in a repository — persistent memory, checkpoints, audited receipts.
A 100-day learning curriculum with two tracks: Backend Engineering and AI Knowledge.
03 My Cosme Products
A personal beauty research station — paste a product name, and AI looks up its price and ingredients, judges whether it suits you, ranks it within its category, and keeps your own usage notes.
04 Kotoba Learning
A tool for learning how Japanese words feel — look one up and get an AI explanation of its meaning, register, tone, frequency and easily confused words, saved automatically to a personal notebook.
