ClickHouse Netherlands User Group

Join us in Amsterdam at Adyen's office for an evening dedicated to how AI is changing the fintech landscape. From agentic copilots in production to what's next for the world's fastest analytical database, this meetup brings together developers, data practitioners, and fintech builders.

Brought to you by ClickHouse and Adyen;
Hosted by Kwok He Chu (Developer Relations @ Adyen) and Tyler Hannan (Global Advocate @ ClickHouse)

🎤 Session Details:

• Alexey Milovidov, co-founder and CTO of ClickHouse, Inc.
  Talk: Alexey will talk about ClickHouse for analytical workloads that leverage vector embeddings and the industry-specific outcomes this enables.
• Iftach Arbel, Senior AI Research Engineer at Adyen. Iftach develops agents and bug the hell out of them.
  Talk: Skills First: How We Shipped an Autonomous Fee Agent Before Writing an Agent Harness
  Description: We built an autonomous agent for a task where reliability mattered most. We will describe agent design patterns to explain our decisions: deterministic vs. agentic behavior, predictability vs. flexibility, auditability vs. adaptiveness, and routing vs. parallelization. These are the four patterns that applies to many agentic systems. Using the agent design patterns, we decided for each behavior whether it belonged in deterministic code or should stay agentic. The surrounding structure (the flow, its guardrails, and the routing between pieces of domain knowledge) moved into code. The core reasoning stayed agentic: the model's calls remained open-ended wherever that flexibility earned better results.
