Jannis Leidel, better known as "jezdez" in the Python community, has until recently been working at Mozilla as a software engineer on the Mozilla data platform team, maintaining part of Mozilla’s data infrastructure and tools and before that as a web developer on the Mozilla Developer Network (MDN) project that documents Open Web technologies. He's now a Software Engineer at Anaconda working to improve packaging for the next generation of Python et al.

As an avid contributor to Open Source projects, he's incredibly proud of the different communities he has become part of, whether it's the Python packaging ecosystem, the data science community, the Django project or the Jazzband collective. As director at the Python Software Foundation he works in the packaging working group, the finance committee and as co-communication chair.
