FullStack Developer - Software Engineer II

• Working on Health Data Repository (HDR) systems using Smile CDR and FHIR R4/R5 APIs to manage and exchange clinical data securely and efficiently.
• Designed, developed, and integrated FHIR-compliant RESTful APIs for core healthcare resources such as Patient, Immunization, Procedure, Observation, and CarePlan using .NET.
• Built secure and responsive frontend applications using Angular, enabling seamless interaction with .NET backend services.
• Designed and optimized FHIR resource fetching, transformation, and aggregation pipelines to support real-time clinical dashboards and healthcare data visualization.
• Implemented Retrieval-Augmented Generation (RAG) workflows to retrieve relevant clinical data from FHIR resources and generate meaningful summaries using Large Language Models (LLMs).
• Leveraged LangChain to orchestrate LLM workflows, prompt templates, and context injection for accurate healthcare data querying and summarization.
• Integrated vector databases and embeddings to improve semantic search and reduce hallucinations in AI-generated clinical insights.
• Developed end-to-end health record visualization solutions, including role-based access control, audit-friendly data flows, and integration layers for external FHIR services.
• Collaborated closely with cross-functional teams (backend, frontend, QA, and domain experts) to ensure FHIR data models, APIs, and workflows adhered to healthcare interoperability standards.
• Actively contributed to improving system performance, security, and maintainability in compliance with healthcare data handling best practices.
