Hi, I'm Atsushi Hatakeyama

On this site, I write about software development, startups, and things I learn through day-to-day experience. My technical strengths are AI system development, software design, and new business development. The languages I use most are Python and TypeScript.

What I do

I write code, explore new technologies, and turn projects I care about into real products. I am especially interested in AI product development, contributing to OSS, and building software that is both functional and inspiring.

What I value

I value simplicity and clarity. I believe good software should be easy to understand, maintain, and extend. More than technology itself, I care about solving real problems, because my way of thinking starts from engineering.

Other work

Beyond software development, I also work on my own business, finance, and education-related activities.

I collect my thoughts in Writing and the things I build in Projects .
