Attendance 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.

Useful tools for people around me, games to play, and small improvements to everyday life.

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.
Internal project
Racing Game
3D driving game built with Three.js and the Rapier physics engine. Includes a headless verification pipeline using SwiftShader for GPU-free automated testing. Design decisions — including why post-processing and IBL were removed — are documented throughout.
Internal project
V-carve Engraver
Python GUI that generates G-code for V-carve CNC engraving from DXF files. Extracts the skeleton with medial axis + distance field to compute per-point carving depth by bit geometry in real time. A 3D simulation replays the exact G-code motion before any real cutting — full pre-flight on the machine.
Internal project
Eiken Quiz App
Flutter app for EIKEN Grade 3 and Pre-2 exam practice. Scrapes irregularly structured URLs, decrypts blank-password PDFs with pikepdf, strips ruby annotations, then serves the content. Gemini grades second-stage writing responses across four criteria (content, structure, vocabulary, grammar) in real time.
Internal project
Daily Poster
SNS automation tool that takes voice or text input, processes it with Gemini, and publishes simultaneously to X (Twitter), note, and Instagram. Runs as either a Flask API or a CLI. Gemini adapts the content to each platform's tone, so you only need to supply the idea.
Internal project
PokerNow AI
Solver-first poker AI using TexasSolver. A browser userscript reads PokerNow game state in real time, forwarding it to a local Flask server that console-drives TexasSolver. Achieves solver-grade accuracy for heads-up situations.
Internal project
kaya-site
This site. Built with Astro, Keystatic CMS, and Vercel. Japanese / English switching, writeups, dark and light themes, with every piece of content editable through the CMS.
