Software Engineer / AI Companion Builder
A software engineer based in Japan, building emotionally persistent AI systems and long-term companion experiences.
Soft interfaces for long conversations.
I care about AI that can stay with people over time: memory, continuity, emotional texture, and the small design choices that make a companion feel present without becoming loud.
What I am working on now.
Small tools made for daily life.
A private personal space for voice logs, English practice, daily notes, small utilities, and archives.
A small self-hosted memo tool for managing notes, todos, accounts, and small records.
A vocabulary tool for saving words from daily English study and reviewing them later.
A small travel and city exploration app for places and shared memories.
