Berlin Meetup

Sharing insights from the data streaming industry

Reserve your seat today!

We invite all real-time and data streaming enthusiasts from industry, academia and beyond.

Flink Forward 2025 may be over but the conversations are just beginning.

This community meetup brings together Flink practitioners and innovators to discuss how Apache Flink continues to shape the future of real-time data processing, from modern data architectures to machine learning in production.

Agenda & Speakers

Title: From GNSS to Insights: Designing a Modern Data Lakehouse with Flink & Iceberg

Speaker: Dhruba Roy, Senior Software Developer at T-Systems
Bio: Dhruba leads the development of a modern data lakehouse for a major customer, leveraging Apache Flink and Iceberg to unify batch and streaming workloads. With expertise in Java, Spring Boot, Kafka, and OLTP databases, he’ll share how GNSS data is transformed from raw signals into business-ready insights.

Title: Logistics Network Optimisation using Apache Flink

Speakers: Dionysios Stolis & Malte Winckler, JustEat
Bio: Dionysios Stolis is a Machine Learning Engineer specializing in distributed systems and productionising real-time ML applications,
Bio: Malte has a background in Applied Mathematics and works as a Data Scientist on the frontier of Statistics and Optimization,

Description: Real-time capacity management in our on-demand delivery platform is built on a careful combination of predictive machine learning models and a business-oriented optimization framework. This is a mission-critical service and demands stateful features computed in real-time. Join this session to discover our architecture around Apache Flink. We'll explore how it empowers our data scientists to run reproducible experiments and enables our ML engineers to deploy a highly scalable, robust system. This talk is for anyone passionate about building real-time machine learning systems and tackling production MLOps.

Networking, Drinks & Pizza

After the talks, stay for networking, free drinks, and pizza with fellow data streamers.
Share ideas, exchange war stories, and discuss what’s next for Apache Flink in 2026 and beyond.
