I'm a web engineer exploring AI coding, AI agents, open source, and side projects through hands-on experiments.
I like building things, measuring what actually happens, and documenting the design decisions and lessons behind them.
OSS Tanbou is an open-source discovery site for finding interesting OSS beyond trending lists.
I collect and follow projects over time using GitHub activity such as stars, commits, issues, and pull requests, while also writing about why a project is interesting, how it is designed, and how it grows after discovery.
AI Dev OS is an open framework for turning tacit development knowledge into explicit, reusable rules for AI coding assistants.
It explores how coding rules, context design, and post-generation review can make AI-assisted development more consistent across tools.
AI Dev Readiness is a self-assessment tool for visualizing how ready a development organization or project is for AI-driven development.
A short questionnaire produces a 100-point readiness score across five axes, an AI adoption level, process-level suitability, priority improvements, and an adoption roadmap. The assessment runs entirely in the browser without requiring login.

Trait Compass is a browser-first self-check and support-navigation app that helps people organize developmental traits and everyday difficulties, then connect them with relevant public support information.
Self-check answers and scores stay in the browser. Support information is built from Tokyo and municipal open data and official sources, while generative AI is limited to optional explanations rather than authoritative facts.
