Before AI could organize my life, I had 43 worktrees to clean up
My personal assistant was meant to help with calendars and email. Its development folders needed attention first.

About
Making things, flying things, taking detours.
Based inJapan
When something makes me curious, I want to try it and understand it for myself. I research security through HackerOne, build FPV drones, and experiment with Raspberry Pi and ESP32 boards.
I build small tools to make everyday tasks easier and things I can learn from while playing: an AI for calendars and email, engraving software, and a racing game. The parts that go wrong also make it into my build outtakes.
Away from the screen, I enjoy the moment when a quad I built takes off, a radio link connects, or a small tool becomes useful to someone. I also enjoy skiing, aerial photography, and learning rope work.

Notes & outtakes
Most builds come with a few detours.
Things that went wrong, small discoveries, and hobbies. The parts you do not see in the finished project.
All writeupsProjects
Things I have been making.
Useful tools for people around me, games to play, and small improvements to everyday life.
All projectsAttendance System
I built a web and Android tool to make attendance tracking for club activities a little easier. I keep improving it while it is being used.
Jiyu Kenkyu AI
I built a system that draws out a child's curiosity through conversation and turns it into a starting point for a research project, while keeping their own words at the center.
Internal project
ZeroTerm
I turned a Raspberry Pi Zero 2 W into a portable Linux terminal that I can control from an iPad. It started as an experiment in making a tiny computer genuinely useful.
AI Life Manager
A Discord Bot that accepts casual DMs and lets a Gemini agent autonomously manage life tasks across 35 tools — Google Calendar, Tasks, Drive, Gmail, Contacts, Docs, Sheets, Outlook, and Obsidian — via function-calling. n8n handles scheduled inbox sorting. Running on WSL2 + Docker.

Interests
Touching systems, away from the screen too.
Drones, Linux, electronics, radio, AI, skiing. One interest led to the next, always hands-on.
Drones
I got into drones after seeing FPV videos on YouTube. These days I enjoy both building my own quads and shooting aerial photos with a DJI Air 3S while traveling.
Linux & Electronics
I use Debian and Ubuntu, explore Arch, and build with Raspberry Pi and ESP32. My projects also include a Python GUI for engraving toolpaths. I enjoy making software connect to physical things.
Security & CTF
Following questions about Linux led me into security. I learn by reporting findings through HackerOne within each program's scope and by working through challenges on TryHackMe.
Building with AI
I use AI as more than a chat partner: it is a tool for turning ideas into working things, including small systems that make daily life easier.
