Summary

I am an AI-focused technology researcher with 5+ years of experience building intelligent software solutions across Generative AI, Agentic AI, semantic search, and backend platform engineering. My work includes enterprise-scale Retrieval-Augmented Generation (RAG), document intelligence, knowledge retrieval, and FastAPI-based services.

At Tata Consultancy Services, I contribute to a custom Semantic Knowledge Engine, supporting document ingestion, parsing, chunking, indexing, embedding generation, metadata filtering, and context-aware retrieval. I evaluate retrieval quality through similarity scoring, ranking, and comparative analysis, while developing APIs and database integrations for enterprise AI platforms.

My personal projects explore multi-agent AI systems, including an autonomous coding assistant using CrewAI and Docker, a deep-research orchestrator using asynchronous agents, and an investment research assistant coordinating specialized agents. These projects reflect my interest in turning LLM capabilities into useful, reliable applications.

Earlier in my career, I worked on the Patent Analytics Tool and data-driven IT operations. I helped analyze 65,000+ monthly alerts for a retail client and developed Power BI reporting that reduced analysis time from hours to minutes.
