Role: Technical Lead
Technologies: .NET Core, HL7, FHIR, CCDA, IdentityServer4, SQL Server, Grafana, Loki, Docker

Project Overview:
Designed and developed FHIROps, a real-time healthcare data transformation engine enabling bidirectional exchange between HL7 v2.x, FHIR R4, and CCDA formats. The solution supports live production use cases including dialysis machine data ingestion, hospital EHR sync, and FHIR-based API integration with smart monitoring and alerting.

Key Responsibilities:

• Architected modular transformation pipelines configurable for any healthcare format.
• Integrated real-time observability with Grafana + Loki to track processing, status failures, and data lineage.
• Developed a custom IdentityServer4-based authentication server to protect APIs and enforce RBAC.
• Worked closely with data teams to build FHIR bundles from OCR/AI-parsed clinical documents (prescriptions, lab results).
• Deployed the solution using Docker and managed via NGINX reverse proxy, ensuring scalability and secure API routing.
• Supported production rollouts for clinics using live HL7 ORU/ADT feeds, ensuring data integrity and compliance.

Raw Materials Availability: Raw material availability is obvious to upstream firms that extract, refine, and process material into products which helps to maintain stock availability and meet customer requirements and Implementing advanced technologies such as real-time tracking, data analytics, and predictive modeling can enhance visibility. Helps proactive monitoring of supply chain events, such as natural disasters, geopolitical issues, or policy changes, can help identify potential disruptions to raw material availability.
