About Hassan
Healthcare AI & HL7 Integration Engineer | .NET | Mirth | FHIR
Rawalpindi, Pakistan - 11:02 pm local time
Most integration work fails in the same three places: malformed segments nobody validates on ingest, channels with no error queue or replay path, and mappings that break the first time a sending facility changes its format. I design for those on day one, not after the first outage.
Healthcare integration
• Mirth Connect — channel development, migration, troubleshooting, performance tuning
• HL7 v2.x — ADT, ORM, ORU, SIU, DFT parsing, transformation, validation
• FHIR ↔ HL7 v2 bridging and resource mapping
• EHR interface work and HIPAA-aware data handling
AI on clinical data
• LLM extraction from unstructured clinical text into structured HL7/FHIR
• RAG pipelines over clinical documentation with de-identification
• .NET 8 services wrapping OpenAI/Anthropic APIs for healthcare workflows
Core engineering
.NET 8 / ASP.NET Core · Entity Framework Core · SQL Server · Angular · Vue · Azure DevOps CI/CD
Recent work: Built and shipped MindBillAPI, a .NET 8 service automating superbill generation and insurance claim workflows for out-of-network mental health practitioners — EF Core data layer through PDF generation to production deployment.
If you have a broken feed, a migration off an aging interface engine, or you're trying to put an AI layer on clinical data without creating a compliance problem — send me your setup and I'll tell you straight whether I'm the right fit.
