Overall security risk & vulnerability score reduced by 87%


Client Background

The client is a federation of 35 separate US-based health insurance companies that serves more than 106 million people


  • A key challenge for the client was an aging data platform which was increasing the licensing and support costs, driving poor business processes, and was leading to missed opportunities
  • The client was also witnessing low levels of maturity in data and its associated governance


  • Created a custom road-map for platform development with realistic time frames and multiple implementation options. It was based on the current platform but also took into consideration both IT and business needs
  • Developed ROI-based models and assisted the client with board-level presentations
  • Implemented the data platform in multiple stages, in combination with decommissioning activities
  • Established governance groups to ensure business and IT can maintain visibility into the implementation
  • Managed & monitored AWS cloud environment & services that include AWS EMR, Lambda, Redshift, Cloud Trail, Cloud Watch amongst others
  • Facilitated operations & support of AWS Data Pipeline, AWS Glue, AWS EMR (DL) & AWS Redshift (DWH)
