Tech Events at Adyen, Amsterdam

with Ayan Banerjee (Feature Platform, Adyen) · Vitalii Zhebrakovskyi (Fraud Detection, Adyen) · Pedro Mazala (Engineer, Ververica)

Production stories about Apache Flink, hosted by Ververica on the 11th floor at Adyen. Ayan Banerjee and Vitalii Zhebrakovskyi, from Adyen's Feature Platform and Fraud Detection teams, explain how Flink computes the real-time features behind fraud detection, scheme routing and bot detection across millions of payments a day. Pedro Mazala of Ververica covers Flink with Iceberg at scale - checkpoint frequency, small files, compaction, snapshot management, sink parallelism and the trade-off between freshness and query performance - and where streaming storage such as Apache Fluss is heading. Engineers from Booking.com also speak. 18:00 to 21:00, free. Why go: one of the few Amsterdam rooms where people running streaming infrastructure at payment scale say what it actually costs. For data and platform engineers already on Flink, or weighing event-driven systems.

Amsterdam's database meetup, hosted at Adyen. AMS DB stays deliberately vendor-neutral and runs across Postgres, distributed stores and the query-engine layer, which makes it a better read on what Dutch engineering teams actually run than any single-product user group.

An AGNTCon pre-day session hosted at Adyen and co-run with the Dutch Cloud Native and AI security communities: what agentic AI looks like once it is actually in production — tool calls, failure modes and securing what the agents can reach.

The Dutch ClickHouse user group at Adyen, whose own analytics stack makes the host a credible source of war stories. Real-time analytics at volume, schema design and the operational side of running ClickHouse in production — a technical evening with an audience of data engineers.

An evening on Rust where it meets data engineering and machine-learning infrastructure, hosted at Adyen. Rust has quietly become the substrate for a lot of new data tooling, and this is one of the few Amsterdam meetups treating that as an engineering topic rather than a language-fandom one.
