Summary
🤩
RockstarDaisuke Maki is a seasoned engineer and tech-PR specialist with 20 years of experience building and maintaining production systems in Perl, Go, and C/C++. Based in Tokyo, he combines hands-on open-source development—authoring projects like peco, STF and the lestrrat-go/jwx JWT library—with event and community leadership, having organized YAPC::Asia Tokyo and founded the Japan Perl Association. He has run a profitable small business (Endeworks) and shipped infrastructure at scale across companies including Livedoor, LINE, HDE, and Mercari, where he now focuses on internal communications and developer relations. A published author of a Japanese modern Perl book and a fluent Japanese/English speaker who also knows some Portuguese, he is as comfortable refactoring cryptography code and YAML parsers as he is running conferences. Notably, his work on jwx and related projects has been adopted to modernize JWT handling in larger OSS projects, reflecting rare depth across libraries, systems, and community ecosystems.
