Hi, I'm Koudai Aono, an OSS maintainer based in Tokyo.

I build and maintain developer tools, especially for Python teams. My projects include datamodel-code-generator, fastapi-code-generator, and PyCharm plugins for Pydantic, Ruff, and Poetry. datamodel-code-generator gets 12M+ downloads per month on PyPI, the Poetry plugin shipped as a built-in feature in PyCharm 2021.3, and I co-authored PEP 750, which adds template strings (t-strings) to Python 3.14.

Most of the work behind these projects is ongoing maintenance: compatibility updates, release engineering, documentation, issue triage, reviewing contributions, and handling edge cases as libraries and specifications evolve.

Sponsorship helps turn that maintenance into dedicated time. It supports faster releases, better documentation, and steadier long-term support across the tools I maintain.

If your team depends on any of these projects, sponsorship is the most direct way to help keep them reliable and moving forward. For individual users, it is a simple way to support tools that make everyday development easier.

Thank you for supporting sustainable OSS maintenance.
