***What’s up, PyData Amsterdam community!

For our next meetup, we are bringing you two massive, real-world migration stories from major engineering teams who tore up the old playbook to build next-gen analytics platforms.

Mark your calendars! We are gathering at the**Xomnia officeinAmsterdamonJuly 30** to dive deep into these architectures over cold drinks and great food.

We are putting the spotlight on Holland Casino and a major public-sector organization to pull back the curtain on their architectural pivots. From open-source dbt workflows to massive PySpark-driven migrations, this event is packed with raw engineering insights you can actually use.

💡 Why you can't miss this:

Two Ecosystems, One Goal: Compare how Databricks + dbt stacks up against Microsoft Fabric + PySpark for Medallion (Bronze/Silver/Gold) architectures. Zero Marketing Fluff: Both talks focus heavily on the real engineering decisions, mistakes made, and lessons learned.

• Community & Networking: Stick around at Xomnia after the talks to grab a drink, talk shop, and swap migration stories with fellow engineers.
