greymoth · Tokyo · proof, not pitch
19, in Tokyo. I build fast, ship into real open-source projects, and keep an honest record of what worked — and what died.
No track record to claim yet, so here are three live, checkable records instead. Every number below is pulled from a public source you can open and verify yourself.
The record
Code a maintainer actually accepted: merged into medusajs/medusa and janhq/jan, with more pull requests still in review. Each merge links straight to its GitHub PR — you can verify the state yourself, and the page reads live from the API so it can't be faked.
→ proof-dashboard /proof-dashboardI scored 40 foreign dev tools on how ready they are for the Japanese market. None had a 特商法 (legally required commerce) page; the average score was 5.6 / 100. Methodology and per-tool breakdown are on the page.
→ japan-readiness-index /japan-readiness-indexA specimen archive of 128 things I built — and the honest part: most of them died. Kept as a dissected record of the work rather than a highlight reel, because the failures are the point.
→ builder-archive /builder-archiveThree merged PRs is a small, early record — I present it as exactly that: live, click-through-verifiable, and growing, not a finished résumé. The point is that every claim here links to a third party (GitHub, Apple) you can check, not a number I typed myself.
Also shipped
A daily music bloom ritual, shipped past Apple's review and live on the iOS App Store (seller: Mahiro Hirakawa). Open the listing — that's the verification; Apple guarantees it, not me.

Everything new ships as a public GitHub repo first. Follow me there and GitHub notifies you the moment the next one lands — no email, no algorithm deciding whether you see it.
GitHub follow = a real notification when a new public repo ships. RSS = subscribe in any reader and own the feed yourself. Both are yours — nothing to unsubscribe you, no algorithm in the way.
Coming soon email list — wiring an owned mailing list
A "get notified by email on launch" list is on the way. It's not live yet — rather than show a button that silently fails, I'd rather be honest and point you to GitHub / RSS above, which work today.
