Become a sponsor to Koki Watanabe

Hi, I’m KOKI Watanabe 🐥

I’m a backend-focused software engineer with a strong interest in machine learning, algorithms, and performance-critical systems.

I contribute to major open-source projects, including NumPy and Polars, and I actively build and maintain libraries and web applications using C++, Python, Rust, and Java.

Sponsorship helps me spend more time on open-source development and long-term maintenance.
As a sponsor, you’ll get prioritized responses to issues and feature requests, as well as thoughtful reviews and improvements.

Thanks for supporting my open-source work!
