  • Holden Karau - Co-Founder at Fight Health Insurance @HoldenKarau
  • Julian Wood - Serverless Developer Advocate at AWS @julian_wood

Apache Spark contributor Holden Karau discusses the evolution of distributed data processing, the challenges of integrating machine learning with big data tools, and the technical complexities of working with GPUs at scale.

The conversation takes a personal turn as Holden reveals her latest project: an open-source AI tool that helps people appeal health insurance claim denials. Drawing from personal experiences with denied claims, she has built a system that trains on independent medical review data to generate effective appeals, making it freely available at https://fighthealthinsurance.com while grappling with the classic open-source challenge of sustainable funding.
