What we’re about
🎉 We are pleased to announce: PyData Frankfurt will soon return as PyData Rhein-Main. STAY TUNED. 🥳
Our meetups feature both local and international speakers.
Whether beginner or expert - everyone is welcome at PyData. Speakers wanted!
Please contribute to our community by sharing your wisdom and expertise, even if it’s just a 5 minute lightning talk. Don’t worry if you are a first time speaker - the experienced speakers in our team are happy to coach you. Contact us.
All our meetups will be held English since we are an international community. We are looking forward to seeing you at our next meetup. Please respect that our community forums may not be used for advertisting or recruiting. Community postings are fine - if you are in doubt just contact an organiser. Please feel free to ping us if you have any questions or suggestions.
See you soon
Team PyData Rhein-Main
PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States. PyData provides a forum for the international community of users and developers of data analysis tools to share ideas and learn from each other.The global PyData network promotes discussion of best practices, new approaches, and emerging technologies for data management, processing, analytics, and visualization. PyData communities approach data science using many languages, including (but not limited to) Python, Julia, and R.The PyData Code of Conduct ([http://pydata.org/code-of-conduct.html)](http://pydata.org/code-of-conduct.html)gove)Â gove...

To discuss any issues or concerns relating to the code of conduct or the behavior of anyone at a PyData meetup, please contact NumFOCUS Executive Director Leah Silen (+1 512-222-5449; leah@numfocus.org ) or the group organizer.We run meetups regularily at changing locations and have organised also the PyConDE & PyData Karlsruhe conference 2017.

Talk #1
An introduction to synthetic datasets to accelerate your LLM projects
Patrick Fleith
Senior Data Scientist | LLM Engineering
Talk #2
Security Risks in AI
Sebastian KrauĂź
AI Test Developer@Validaitor
In this session, we’ll take a closer look at the security risks that come with integrating LLMs into applications. LLMs can be powerful allies in cybersecurity — helping with detection, testing, and protection — but they can just as easily be exploited for attacks. We’ll explore key threats such as prompt injection, jailbreaking, and agent-specific vulnerabilities, and discuss why they are currently seen as the most pressing risks. Finally, we’ll look at defense strategies, from prompt-level safeguards to system-wide controls, and show how best practices can make a real difference in securing AI systems.
About the Speaker
Sebastian is an AI Test Developer at Validaitor. With a background in Mechatronics and Autonomous Systems, and hands-on experience at Bosch, Fraunhofer, and in international research settings, Sebastian focuses on the intersection of AI robustness and real-world deployment. His current work involves developing methods to test AI models for vulnerabilities, adversarial risks, and secure behavior—ensuring AI systems perform reliably and ethically.
Talk #3
Structured Automation with Agentic AI: Lessons from Community Operations
Alexander C. S. Hendorf
AI & Data Strategy and Implementation @ opotoc GmbH
This talk presents a technical case study of applying agentic AI systems to automate community operations at PyCon DE & PyData, treated as an open-source testbed. The key lesson is simple: AI only works when put on a leash. Reliable results required good architecture, a clear plan, and structured data models — from YAML and Pydantic schemas to reproducible pipelines with GitHub Actions. With that foundation, LLM agents supported logistics, FAQs, video processing, and scheduling; without it, they failed. By contrasting successes and failure modes across different coding agents, the talk demonstrates that robust design, validation, and controlled context are prerequisites for making agentic AI usable in real-world workflows.
About the Speaker
Alexander is a data intelligence and AI expert with over 20 years of experience in digitalization and data-driven decision-making. As an independent consultant, he's specialized in AI & data strategy and implementation. A frequent speaker and chair at international conferences like PyCon DE, PyData Berlin, and EuroPython, he is also a Python Software Foundation Fellow and EuroPython Fellow. He serves on the board of the Python Software Verband and, since 2024, has also been leading Pioneers Hub, a non-profit dedicated to supporting tech communities.
