About
Kaoru Shiina, also known as SHIINASAMA. I'm an independent developer focused on building tools that respect how people actually work — fast, native, and distraction-free. Most of my work lives at the intersection of macOS desktop apps and developer tooling.
I believe good software disappears into the task it serves. The best tools are the ones you stop noticing — they just work, and they stay out of your way. That philosophy drives everything I build, from Wi-Fi analyzers to chart libraries to CLI scaffolding.
I work primarily in Swift, Rust, and TypeScript. Most of my projects are open-source because I think readable, inspectable code is part of building trust. When I'm not shipping software, I'm writing about the craft — usually on Medium.
