Distributed services replacing legacy monoliths
Problem
A major regional healthcare provider depended on legacy monolithic systems that struggled with high-volume transactions across patient records, claims processing, benefits management, and operational workflows. The target architecture needed predictable scaling, strong data consistency, and operational resilience without disrupting care delivery.
Solution
As technical lead for backend development, I drove the migration toward microservices and a distributed architecture on Azure. Backend services were implemented around clear domain boundaries for patient data, claims, benefits, and workflows, using Redis for performance-sensitive paths and SQL Server where transactional integrity was critical.
Architecture decisions
- Service boundaries were aligned to healthcare domains so teams could evolve claims, benefits, and patient workflows without collapsing everything into a single deployment unit.
- Redis supported high-read patterns and transient state while SQL Server remained the system of record for durable healthcare data.
- Azure-hosted infrastructure supported elastic capacity and platform-managed reliability patterns appropriate for regulated workloads.
Impact
- Established a modern microservices foundation capable of absorbing continued migration from legacy systems.
- Supported high-volume transactional workloads with consistency and resilience as first-class requirements.
- Coordinated engineering execution across a 52-person cross-functional organization.
