Experienced in building agentic AI systems and multi-agent workflows using LangChain and LangGraph, enabling coordinated reasoning, planning, and tool execution across autonomous agents. Skilled in implementing Retrieval-Augmented Generation (RAG) pipelines to enhance contextual accuracy and reduce hallucinations. Applied LLMOps for prompt versioning, traceability, evaluation, latency monitoring, and reliability improvements. Designed specialized role-based agents and enabled structured delegation using Agent2Agent communication protocols. Integrated Agntcy Identity, Observe, and Directory to standardize behaviors and improve observability. Implemented high-performance telemetry pipelines using ClickHouse, Grafana dashboards, and the OTEL Collector, ensuring real-time monitoring, performance optimization, and scalable deployment of agentic AI workflows.

I Spearheaded the development and deployment of Gen AI Retrieval‑Augmented Generation (RAG) chatbots, significantly improving enterprise knowledge retrieval, customer support automation, and user experience. Using LangChain and LangGraph, I architected modular agent‑based workflows that enabled autonomous reasoning, contextual memory retention, and efficient multi‑turn task execution. These intelligent agents leveraged OpenAI’s GPT‑4, Pinecone vector databases, and hybrid retrieval strategies for contextually accurate and knowledge‑grounded responses. I implemented advanced prompting techniques—including Chain‑of‑Thought, Zero‑Shot, and Few‑Shot learning—to optimize LLM performance for complex reasoning tasks. Through custom embeddings, memory‑backed retrieval, and LLM fine‑tuning with PEFT and quantization, I reduced inference latency while enhancing model accuracy and efficiency. I also automated summarization workflows, integrated knowledge graphs, and used NLP libraries for sentiment analysis across healthcare and enterprise datasets. Additionally, I applied these Gen AI frameworks to credit risk assessment, fraud detection, and anti‑money laundering (AML) initiatives, enabling proactive risk management, regulatory compliance, and enhanced decision‑making in financial operations.
