Hi there! My name is Sydney Runkle, and I'm excited to announce my nomination for the PSF Board. I'm primarily known in the Python community for maintaining open source projects, most notably pydantic
and tools in the langchain
suite. I'm also an active member in the talks circuit and a frequent Python/AI podcast guest. I'm eager to bring a passionate perspective to the bigger picture of Python's development.
Background
Interestingly, my fascination with Python all started because of a sledding accident. One broken leg later, I was confined to a wheelchair and in desperate need of a new hobby. My dad handed me an introductory Python book, which quickly evolved into a deep dive in courses on data science, machine learning, and applied stats.
I began working on projects like plotting bird migration tracks, analyzing US election data with streamlit
, and generating plotly
visualizations for articles I was writing for the local newspaper. One of the most rewarding projects was working with a local nonprofit PORCH to optimize non-perishable pickup routes with an interactive map application.
Service
My career has been largely focused on open source development. I take a unique approach to open source maintenance, a "kill 'em with kindness" philosophy, if you will. Open source is grounded in relationships, conversations, and effective collaboration. I'm looking to bring this same approach to the PSF Board.
Open Source Contributions
- pydantic lead maintainer (2024-2025)
- pydantic-ai maintainer (2024-2025)
- langgraph lead maintainer (2025-current)
- langchain maintainer (2025-current)
- streamlit early user and collaborator with devrel team (2019-2020)
Miscellaneous
- PyConUS 2025: Reviewed 600+ talk proposals with detailed ratings and feedback
- School Improvement Team Board Member: Served a 2 year term, learning effective governance
- Hunger Relief Club President: Recruited volunteers, organized fundraisers, and coordinated advocacy campaigns
Initiatives
If elected, I plan to lead work on the following initiatives:
- AI Education: Python is the top language for AI development, but the PSF has yet to significantly invest in educational resources surrounding emerging patterns for AI use with Python. My experience with both
pydantic-ai
and thelangchain
suite of tools makes me uniquely qualified to help advance this initiative. - PyPride 2026: Python has many groups bringing together underrepresented communities (like PyLadies), but I don't think enough has been done to celebrate the LGBTQ+ community in Python. I'd like to help organize and fund a PyPride event in June of 2026 (and future years) to bring together a community that's not often represented fully or seen.
- "Zero to Speaker" Pipeline: I feel lucky to have spoken at a variety of Python conferences, but I don't feel like there were adequate resources encouraging young speakers to get involved. I'd like to change that. My experience both giving and reviewing talks will help me to demystify this process.
