Thea "Stargirl" Flowers

I am a developer advocate, software engineer, and hardware designer. It is my mission in life to empower people of all backgrounds using open source software and hardware.

I am most known for my work in the Python community. I have been the maintainer of critical community-owned open source projects like urllib3, Twine, and packaging.python.org. I’ve organized incredibly diverse and engaging conferences like PyCascades and given talks at dozens of meetups and Python conferences. I’ve volunteered my experience as an organizer, speaker mentor, and diversity expert to several conferences. I have been recognized as a Python Software Foundation Fellow for my work in the community.

I'm also the owner of an independent, boutique synthesizer company, Winterbloom. I design and manufacture Eurorack-format modules that are completely open-source.

I have deep experience with open source, developer tooling, technical writing & communication, community organization & engagement, public speaking, and API design. In addition, I have a broad history of experience with topics such as computer graphics, video games, embedded systems, front-end development, mobile development, reverse engineering, and robotics.

As a technical leader and individual contributor, I bring a wealth of experienced vision, guidance, and contributions to the teams, projects, and organizations that I interact with. My focus is always on empowering others to accomplish their goals by removing barriers, navigating ambiguity, building relationships, and detailed technical design.

My work has been featured in several articles and interviews.
