• LLMs, Azure OpenAI, Prompt engineering, Embeddings, Azure Document Intelligence, Retrieval Augmented Generation (RAG), LLM evaluation, Hallucination mitigation, Multiagent frameworks, agent orchestration, autonomous agents, workflow coordination, planner-executor patterns, complex AI workflow design

• Hands on experience with LangChain, LlamaIndex, Hugging Face Transformers, LangGraph, CrewAI, and AutoGen

• Root cause analysis, system design trade offs, optimization for cost, performance, and scalability.

• Experience building NLP and LLM powered solutions for text classification, entity extraction (NER), semantic search, summarization, and question answering in enterprise applications

• AI security best practices, vulnerability management, access control, compliance, responsible AI governance

• Familiarity with UI tools like Streamlit, Chainlit, and API Frameworks like Flask, FAST APIs, Rest APIs, REACT etc

At UnitedHealth Group, our mission is to help people live healthier lives and make the health system work better for everyone. We believe everyone - of every race, gender, sexuality, age, location and income - deserves the opportunity to live their healthiest life. Today, however, there are still far too many barriers to good health which are disproportionately experienced by people of color, historically marginalized groups and those with lower incomes. We are committed to mitigating our impact on the environment and enabling and delivering equitable care that addresses health disparities and improves health outcomes - an enterprise priority reflected in our mission.
