Led development of a microservices-based Pharmacy Management System using C# and .NET Core, applying Domain-Driven Design and Event-Driven Architecture while ensuring HL7, FHIR standards and HIPAA compliance. Built REST APIs to integrate with other services, enforced IP restrictions, security measures, and caching via API Management. Optimized PostgreSQL query performance with indexing and partitioning for real-time medication tracking and implemented row-level security to ensure data privacy. Introduced Role-Based Access Control (RBAC) using Azure AD with OAuth 2.0 and OIDC for granular access across 50+ roles. Architected real-time notifications with SignalR and inter-service communication with gRPC, achieving sub-100ms latency. Implemented unit tests with xUnit, Moq, and Cypress, achieving 95% code coverage and a 30% reduction in post-release defects. Deployed hybrid cloud architecture combining Kubernetes for containerized microservices with Azure Functions and Logic Apps for event
