**Fabric Data Warehouse with Tino Tereshko** For our June meetup, we’re excited to welcome Tino Tereshko, Partner Director of Product at Microsoft, responsible for Fabric Data Warehouse. Having previously spent several years at Google working on BigQuery, Tino later co-founded MotherDuck — the DuckDB-based SaaS analytics platform — before joining Microsoft to lead Fabric Data Warehouse. It’s fair to say Tino knows a thing or two about modern analytical databases. Tino is visiting from Seattle and has kindly offered his time to present at our London user group. The session will include an introduction to Fabric Data Warehouse, an overview of recent developments and future direction, followed by an open “Ask Me Anything” discussion where attendees can quiz Tino on all things data warehousing, Fabric, and analytics. **Agenda** 18:30 - Welcome, drinks, pizza & networking 19:00 - Main Session 20:30 - Close **Venue** Tenth Revolution offices in London. Aldgate House, 33 Aldgate High St, London EC3N 1DL Please provide your first and last name when registering for the event, as this is provided to building security to allow you entrance into the venue.

**We're back at Salisbury House for our summer London Airflow Meetup! Join fellow members of the data engineering community for an evening of engaging talks, great food and drinks, and exclusive swag!** **PRESENTATIONS** ***Talk #1: The Orchestration Layer: A Blueprint for Scaling Dynamic DAGs with Integrated Data Quality Gates*** * **Speaker**: [Vasudev Maduri](https://www.linkedin.com/in/vasudevmaduri/), Staff Data Engineer, Admiral Group Plc Ensuring high-quality data, accuracy, completeness, and schema validity is essential for building data trust. However, scaling data quality checks across diverse datasets often leads to duplicated boilerplate Python code, human error, and a massive bottleneck for Data Engineering teams. In this talk, we’ll explore how to shift data quality from a backlog of tech debt into an automated, self-serve developer experience directly tied to Airflow. We will demonstrate how to build a multi-faceted data observability framework that empowers end-user teams to define their own DQ rules without writing any Python code. By hiding complex Airflow code, users simply select their parameters—YAML configurations that instantly translate into fully dynamic, end-to-end DAGs, including in-flight data quality gates. The core of this session focuses on the technical implementation of integrated DQ checks that live directly *inside* the generated pipelines. You’ll learn how this metadata-driven approach enables a "shift-left" strategy for data observability, automatically enforcing data contracts and routing alerts without manual engineering intervention. ***Talk #2: Self-healing Data Pipelines in Airflow*** * **Speaker**: [Nilesh Khandalkar](https://www.linkedin.com/in/nileshskhandalkar/), Senior Manager, Capgemini Modern data pipelines remain largely reactive—failures trigger alerts, manual retries, and ongoing operational overhead for engineering teams. As systems scale, this approach introduces fragility, delays, and growing complexity in maintaining reliable workflows. This session explores how to design self-healing data pipelines in Airflow using practical patterns such as intelligent retries, conditional branching, and targeted recovery mechanisms. Real-world failure scenarios are used to illustrate how pipelines can detect issues, trigger remediation steps, and resume execution without full restarts or human intervention. The session also looks ahead to how AI-assisted anomaly detection can further enhance these systems by identifying unexpected patterns and enabling more proactive, resilient data workflows. ***Talk #3: What We Got Right (and Wrong) Building a 50-Source Data Platform on Airflow*** * **Speaker**: [Arnaud Caldow](https://www.linkedin.com/in/arnaud-caldow-384423142/), Senior Data Engineer at Collibra Collibra helps enterprises govern their data, but how does Collibra's own data team manage the data that powers the business? The answer is an Airflow-based platform that stitches together dlt, dbt, Kubernetes and Collibra's own product for governance -- all orchestrated through 87 DAGs serving 12 business domains. This talk traces a data point's journey through the stack: from API extraction via dlt pipelines running inside KubernetesPodOperator pods, through a layered dbt architecture where platform engineers standardize data and analysts build business models on top, into analytics outputs that serve multiple business teams, and finally back into Collibra Data Governance via reverse-ETL integration DAGs. Along the way, I'll share the patterns that emerged from operating this at scale: how we evolved from one-off custom pipelines to a reproducible framework that's documented well enough for AI subagents (or a new hire) to generate models from scratch, how our own Pod Operators let us test feature branches on shared environments, and how we're leveraging that same mechanism to migrate from Redshift to BigQuery (and from Airflow 2 to Airflow 3) without downtime. Behind the scenes, a 1Password-backed pipeline diffs credential hashes nightly, catching rotations before they break a DAG. **AGENDA** * **5:30-6 PM:** Arrivals, networking, food & drinks * **6-7:45PM:** Presentations * **7:45-8PM:** Networking

Give up the city streets for a day and breathe some fresh air. Improve your overall fitness levels and make some new friends at the same time. Social Event: Our walks are social walks, where the emphasis is on meeting new people, enjoying nature, healthy exercise, and fresh air. Our walks are not interrupted with running commentaries or historical lectures, although occasionally features of significance may be pointed out. As such our walks will be continuous with few stops and it is your responsibilty to keep walkers ahead in view and to follow the direction of the walk. We always end the walk at a pub where the socialising can continue. Take this opportunity to visit green parts of London, unknown to most people, and that you would not otherwise have an opportunity to see. RISKS:Please dress appropriately for weather conditions and carry a bottle of water and necessary medication. You need to be moderately fit for this walk and be able to walk for four miles without a break. In these walks we use; pavements, cross busy roads, public parkland, towpaths alongside water, other public paths, and tracks through woodland and countryside. Please only wear good sturdy shoes, trousers are recommended, and take care as surfaces may be uneven, and some paths are also used by joggers and cyclists. Be wary of portruding tree roots and low overhanging branches. If you require insurance for these walks then you must arrange this yourself. No large dogs or small children please. Please arrive in good time to allow opportunity to use toilets at the start of the walk as there may not be any toilet breaks available during the walk. WANT TO COME ON ANOTHER WALK?

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
