Architected a production-grade agentic RAG support system using LangChain,
LangGraph, and OpenAI APIs with ChromaDB vector database. Integrated tool-use capabilities enabling the agent to
autonomously raise Jira tickets when customer issues are detected — reduced ticket resolution time by ~40% across
product policy, returns, and order queries. Agentic SRE Agent: Built an autonomous SRE AI agent using LangGraph and Claude as LLM to handle DevOps
operations (SSL/TLS renewals, domain renewals, AWS health checks) without human intervention, cutting operational
toil by ~70%. Backend Development: Contributed to e-commerce backend services in Node.js using repository design patterns for
maintainability and scalable separation of concerns.
