Building practical software with curiosity, creativity, and a little plushie magic.
I'm an independent developer based in Japan. I build browser utilities, work with web technologies, and explore Linux and cross-platform development through open source. My independent cybersecurity research focuses on organizing public evidence into useful, clearly sourced technical resources.
A blue dragon plush, a floating balloon, and a few soap bubbles: a little softness alongside careful engineering.
- PHP Simple Check — A Chromium extension and userscripts for Safari and Firefox for Android that identify observable PHP signals and explain the verdict. A stack fingerprinting utility, with the limits documented in the project.
- Outrage Mute — A browser extension and userscripts that use local dictionaries and heuristics to blur or hide inflammatory posts on X. Configurable filtering, with no external scoring service.
- quake3-quickjoin — Small protocol handlers that connect browser links to Quake III clients. Linux is documented as tested; Windows and macOS scripts still need validation on their respective platforms.
- DeckDroid-Quest3 — My Quest 3-focused fork of DroidDeck, with KGSL compatibility, rendering and suspend-policy changes. Builds on the upstream team's work; device compatibility and hardware validation remain limited.
- Next-Gen Potato Gaming v2 — A personal CachyOS gaming setup guide covering Proton, drivers and launch options. Documentation rather than a standalone application; results depend on hardware and software versions.
Infosec Briefing organizes public cybersecurity information into sourced reports, structured registers and verification tools. Dated findings retain their context, with reported claims, confirmed facts and unknowns kept distinct.

Sponsorship helps fund maintenance and bug fixes, compatibility improvements, testing, documentation, and continued independent open-source development.
