18:00 - Maksym Dibrov (Solidgate) - "How to rewrite a microservice in Python"
About topic: Behind the curtains of Reporting API (https://docs.solidgate.com/reporting/) of global payment orchestration platform. How and why it was rewritten from Java to Python, what were the problems along the road? Great knowledge for all Python devs and Data Engineers engaged in development.
About speaker: Maksym has been working in the global payment orchestration platform as a Data Engineer for 4 years. Engaged in both architectural decisions and hiring into Data Engineering team. Before that Maksym's been working in Finance. He is AWS Certified Data Engineer, ACCA Ceritified accountant (from my time in Finance) and also had a pleasure of making a small, non docs related, contribution to the Airflow project before the rise of AI.

18:45 - Radek Sienkiewicz (VelvetShark) - "OpenClaw in Practice: Building Useful Agentic AI Workflows"
About topic: OpenClaw is an open source, self-hosted AI agent that connects LLMs with real tools, services, local data, and everyday workflows.
In this talk, I’ll use OpenClaw as a practical case study for how agentic AI works beyond demos. We’ll look at its architecture, how it connects to external tools and personal systems, how skills extend what the agent can do, and what makes self-hosted agents different from closed assistant products.
The focus will be practical: what OpenClaw can already do today, where agents are genuinely useful, and where the current limitations still are. I’ll show examples around research, coding, notes, automation, and custom workflows, with the goal of giving engineers and AI practitioners a clearer mental model of what it takes to make agentic AI useful in real work.
About speaker: Radek Sienkiewicz is an AI consultant and one of the maintainers of OpenClaw, an open source self-hosted AI agent. He helps companies adopt AI across products, workflows,
