About Saranya Chakravarthy

I\'m a Senior Generative AI Engineer with 12+ years of experience turning enterprise data into intelligent, autonomous systems — from RAG-powered conversational AI and agentic multi-LLM workflows to NLP pipelines and full-stack data science.Currently at NRG Energy, I architect and ship production-grade Generative AI solutions using LangChain/LangGraph, AutoGen, Azure OpenAI, GPT-4, LLaMA, and vector stores like Pinecone, Weaviate, and FAISS. I build multi-agent systems with ReAct and Plan-and-Execute patterns, LLM-as-Judge evaluation pipelines, and hybrid RAG architectures — all with strict governance, hallucination detection, and NIST AI RMF compliance baked in.Previously at the State of Maryland DoH, I engineered end-to-end ML pipelines on GCP Vertex AI for fraud detection, eligibility verification, and risk scoring, while building early RAG and embedding-based retrieval systems that evolved into full agentic AI workflows. Before that, at Intuit and Cigna, I fine-tuned BERT, RoBERTa, and T5 models for domain-specific NLP — claims classification, NER, document intelligence — and delivered scalable full-stack Python applications across healthcare and finance.My passion spans the full modern AI stack:Generative AI & LLMs — GPT-4o, Claude 3, LLaMA 3, Gemini, Mistral, Falcon, MixtralRAG & Agentic Frameworks — LangChain, LangGraph, AutoGen, CrewAI, Semantic KernelFine-Tuning & Alignment — LoRA, QLoRA, PEFT, SFT, DPO, instruction tuningLLM Evaluation — RAGAS, BERTScore, ROUGE, LangSmith, hallucination & faithfulness scoringMLOps at Scale — MLflow, Kubeflow, Airflow, Docker, Kubernetes, Triton, vLLM, CI/CDCloud-Native Deployment — AWS SageMaker/Bedrock, Azure OpenAI/ML Studio, GCP Vertex AII\'ve delivered AI solutions for NRG Energy, State of Maryland, Intuit, Cigna, and ADP — spanning finance, healthcare, and insurance. If you\'re building GenAI systems, RAG pipelines, agentic workflows, or production MLOps infrastructure and want someone who can move from architecture to deployment (and still write clean Python on day one), let\'s connect.
