As is tradition on the last Friday of the month, CDT HUB hosted the 57th edition of the Python Belgrade meetup, where participants had the opportunity to attend highly engaging talks on user behavior analysis and Large Language Model (LLM) routers.

Vladimir Kukushkin, Senior Data Analyst at Simple App, introduced attendees to Retentioneering, a powerful Python library for analyzing clickstream data. Participants learned how this library is used for user segmentation and identifying patterns that lead to conversions or churn. Vladimir also demonstrated how Retentioneering integrates seamlessly with Jupyter for efficient data processing, providing valuable tools for data-driven product optimization.

Dory Zidon, Founding Engineer and Director of Europe Martian, presented key principles for building scalable inference servers and optimizing them for real-world applications. Particularly interesting was the introduction of the Martian Adapters open-source library, which simplifies working with hundreds of models in a consistent manner. Attendees gained insights into efficiently utilizing LLMs, whether managing a single model or developing enterprise-level projects.

We thank all participants and speakers for their excellent presentations and look forward to the next gathering of the Python Belgrade community!
