The Engineering Challenge /

What Was Broken?

Healthcare operational suites require strict regulatory security, multitenant clinic isolation, and fast retrieval of clinical records without exposing patient data across tenant boundaries.

The Architectural Solution /

How We Solved It

Engineered secure backend REST APIs in ASP.NET Core with Entity Framework Core, structured with multitenant data query filters, granular role authorization, and deployed on enterprise IIS server environments.

System Components & Architecture:

  • ASP.NET Core Web API with global query filters enforcing tenant boundary checks on every database transaction
  • Entity Framework Core repository patterns optimized with indexed queries for fast clinical lookup times
  • Angular frontend portal integration consuming documented RESTful endpoints with reactive state management
  • IIS web server hardening, SSL termination, and structured exception logging protecting sensitive API boundaries

Engineering Highlights & Benchmarks:

  • Implemented strict tenant scoping preventing cross-tenant data leakage at the ORM layer
  • Engineered automated database migrations with rollback capability for enterprise deployments
  • Designed clean API contracts supporting multi-role clinical workflows (administrators, clinicians, staff)
