Building self-healing Airflow pipelines at ATC Drivetrain

At Lyft, a small data engineering team supports dozens of scientists and analysts who tune driver pay configurations on demand, all under SOX controls. In this episode, Ken Obata, Senior Software Engineer at Lyft, joins Kenten Danas to walk through how his team built self-service Dags with an event-driven integration between GitHub Actions and Airflow, and how they solved the data modeling and consistency problems that came with it. Key Takeaways: 00:00 Introduction. 02:49 How Airflow r...

Running Airflow with a one-person data engineering team means every decision about cost, tooling, and best practices has to earn its keep. In this episode, Kenten sits down with Aniruddha Sengupta, Staff Data Engineer at Insignis, to talk through how the UK cash-savings fintech runs a low-cost, scalable Airflow platform. The conversation covers observability, DAG-level best practices, the internal tools Insignis built to control costs, and where AI fits into the roadmap. Key Takeaways: 00...

Scaling Airflow to over 1,000 active DAGs on a team of 3-4 engineers takes structure. In this episode, Kenten Danas talks with Matt Stavinga, Data Engineer at Idelic (now part of Descartes), about how his team standardized DAG creation and logging, built a Jenkins-driven testing workflow with per-PR Airflow environments, and is opening up DAG configuration and triggering to their own customers through the Safety Suite UI. Key Takeaways: 00:00 Introduction. 01:40 Idelic's mission: collecting...

Running LLMs over sensitive data means external APIs are off the table, but open-weight models still need reproducibility, validation, and a paper trail before downstream systems can depend on their output. In this episode, Kenten is joined by Chhayank Jain, Senior ML Engineer at Visa, to talk through how Airflow orchestrates local LLM pipelines end to end: nightly inference over millions of records, silent failure handling with Pydantic and distribution checks, and using a separate DAG to ma...

Security is one of the least visible parts of Airflow for most users, but it shapes what features teams can turn on in production. In this episode, Kenten Danas talks with Anish Giri, Senior Software Engineer and active Apache Airflow contributor focused on security, about three recent contributions that touch nearly every Airflow 3 deployment: hardening connection testing, adding JWT revocation, and splitting execution tokens by scope. Key Takeaways: 00:00 Introduction. 01:16 Anish's ins...
