I build things, break things, and occasionally ship things.
Based in Japan. Fullstack dev with a thing for blockchain, security research, R&D, banking and trading systems.
Still in the trenches βοΈ, and currently deep into Rust, SvelteKit, and making crypto do what I want.
- Secret super project β multi-strategy crypto money grabbing platform and salada (Rust + SvelteKit + the kitchen sink)
- Whitehat security β vuln research, PoC development, responsible disclosure
- Trading tools β some calculators, order flow and footprint analysis, automation experiments and stuff (why not)
- Aptos β full porting of a lot of solidity contract into move for Hashpalette / Osaka Expo after Aptos acquired Hashpalette (late 2024)
- Hashport β built the Hashport Wallet (released Oct 2025), and some other stuff I can't talk about it yet.
- Datachain β here too I can't talk about it yet.
- Government / banking systems β because someone has to, but also can't talk about it yet.

whatever catches my attention and won't let go

To redo.... one day. Probably. Maybe. When the stars align and I run out of other things to build.
Explore the repos, poke around, break stuff (responsibly). Contact me wherever you found me. π«
