## About

I am a GenAI & Agentic AI Engineer with 3\+ years of experience building, evaluating, and deploying production\-grade AI systems at enterprise scale\. At Optum \(UnitedHealth Group\), I specialize in designing multi\-agent LangGraph workflows, high\-throughput FastAPI backends, and advanced RAG architectures that process over 800,000\+ daily production requests\. My core focus is bridging the gap between cutting\-edge LLM capabilities and reliable, production\-ready backend systems\. Core Technical Expertise: • Agentic AI & Orchestration: Multi\-Agent LangGraph Workflows, LangChain, Tool & Function Calling, Prompt Engineering • RAG & Search Systems: Dense Embeddings, Semantic Chunking, Hybrid Search, BERT Cross\-Encoder Reranking, ChromaDB, PostgreSQL \(pgvector\) • Custom LLMOps & Evaluation: Programmatic Benchmarking Frameworks, Precision/Recall/F1 Tool Validation, Model Observability, LangFuse and OpenTelemetry • Backend & Microservices: Python, FastAPI, Node\.js, Distributed Systems, Event\-Driven Architecture, Async REST APIs • Cloud & Security: Azure OpenAI, AWS \(EC2, S3, Lambda\), Docker, OWASP Security, OAuth 2\.0 / JWT Currently based in Gurugram, India and open to high\-impact roles locally, as well as overseas relocation opportunities in Singapore and UAE\.

## Work experience

Senior Software Engineer \- GenAI and AI Systems at Optum, Aug 2026 \- Present · 3 mos, Gurugram, Haryana, India · Hybrid

Software Engineer \- GenAI & AI Systems at Optum, May 2023 \- Aug 2026 · 3 yrs 4 mos, Gurugram, Haryana, India · Hybrid, • High\-Scale Multi\-Agent Orchestration \(MCP\): Engineered and deployed production multi\-agent workflows using LangGraph / LangChain integrated with MCP standards, Azure OpenAI, and FastAPI backends; applied prompt versioning and dynamic model routing across an enterprise platform processing 800,000\+ daily requests\. • Commerce Workflow Automation Safety Guardrails: Automated complex insurance sales and commerce transaction workflows by engineering autonomous AI agents with custom safety guardrails and Human\-in\-the\-Loop \(HITL\) approval gates, eliminating multi\-screen navigation and reducing operational processing effort by 70%\. • Enterprise RAG Architecture Grounding: Built an advanced RAG pipeline for unstructured/structured insurance policy data using semantic chunking, dense embeddings, hybrid retrieval, and BERT Cross\-Encoder reranking on pgvector / ChromaDB , decreasing decision\-making time by 35%\. • Custom LLMOps Enterprise Observability Transition: Architected a code\-based custom evaluation engine using golden datasets to validate tool selection accuracy and extraction Precision, Recall, and F1\-Scores; scaled production reliability by transitioning from custom evaluation harnesses into an enterprise Langfuse and OpenTelemetry \(OTel\) tracing and observability stack\. • Multimodal Document Verification \(KYC/Onboarding\): Owned end\-to\-end development of a real\-time document validation microservice using multimodal OCR to verify uploaded customer records and onboarding documents during live sales transactions, reducing manual effort by 60%\. • Real\-Time Agent Interfaces Streaming: Built responsive streaming UI components in React / TypeScript integrated asynchronously with backend LangGraph engines to deliver low\-latency, multi\-turn agentic interaction\.

## Education

Bachelor of Technology \- BTech, Computer Science, Kalinga Institute of Industrial Technology, Bhubaneswar
