My name is Kohei Koyanagi (小柳耕平) — a full-stack engineer, problem solver, and creator of:
I build things that make life a little simpler and more fun. Whether it's helping friends split expenses fairly or automating a chaotic workflow, I love turning small frustrations into clean, working systems. My background in mathematics and my career in international projects taught me how structure and empathy can meet — both in people and in code.
Labxbit (pronounced /ˈlæbɪt/) is the trade name of my sole proprietorship. The playful name, combining lab and bit, reflects my belief in creating new solutions through technology. This site, labxbit.com, is where I experiment with ideas — from app development and AI to philosophy and design. I hope something here sparks your curiosity, as it does mine.
Thanks for stopping by!
