Case Study 1: Federated GraphQL Modernization for a Global Health Benefits Organization

Challenge

Fragmented APIs and duplicated authorization logic slowed development and degraded user experience across web, mobile, and chat channels. Incremental fixes could no longer meet rising performance expectations.

Approach

Krishna unified the client’s fragmented API ecosystem into a federated GraphQL Supergraph, enabling fast, consistent, and authorization‑aware access to consumer data. Using Aha! for strategic alignment and Rally for execution, he established schema governance and telemetry frameworks to ensure sustainable growth.

Impact

  • Unified data contract across all channels
  • Scalable foundation for emerging AI‑driven use cases

Case Study 2: Consolidating Legacy Billing Systems for a Modern Medicare Experience

Challenge

A leading U.S. health insurer relied on multiple legacy billing systems to manage its Medicare Advantage and Medicaid plans. This fragmentation created high administrative costs, inconsistent member experiences, and ongoing reconciliation issues with CMS.

Approach

Krishna used the migration to Oracle Revenue Management & Billing (ORMB) as a catalyst to rebuild the entire revenue‑cycle foundation. The transformation leveraged the following Oracle’s capabilities:


  • Consolidation of Legacy Systems


  • Member 360 for Transparency & First‑Call Resolution


  • Configurable Pricing & Billing Rules


  • Automated Reconciliation & Dispute Management



  • Streamlined Financial Operations


Impact

  • Improved operational efficiency through automated workflows, rules‑based billing, and centralized reconciliation.
  • Simplified enterprise operations, reducing manual effort and eliminating system‑to‑system inconsistencies.
  • Elevated member experience, supported by transparent billing, accurate subsidies/penalties, and unified Member 360 data.
  • Better support for CMS Star Ratings, driven by improved billing accuracy and member satisfaction.
  • Stronger scalability, enabling the insurer to adapt quickly to new Medicare and Medicaid requirements.
