Built a claims data and identity infrastructure platform to bring visibility, auditability, and reliability to payer-provider billing at scale.

Context

Envision Healthcare's payer-provider billing ran through 835 and 837 EDI files that had never been fully modeled or connected to a single source of truth, while a legacy identity system caused constant application timeouts for clinical staff. Revenue was being lost somewhere inside that opacity, but nobody could point to exactly where.

What I Did

• Built a daily ingestion pipeline linking Envision's on-premise billing monolith with provider 837 files and payer 835 files, with full traceability and auditability across the entire billing lifecycle — procedure to outcome to invoice to receipt.
• Oversaw requirements definition and data warehouse schema design, balancing reporting depth against performance.
• Partnered directly with Envision's HIPAA compliance team throughout, so every stage of data handling and reporting was reviewed against regulatory requirements as it was built.
• Migrated Envision's identity and access management to serverless AWS infrastructure, implementing automatic warm-ups and graceful failure handling to eliminate the timeouts that had been logging clinicians out mid-task.
