## About

```text
At Virtusa Corporation, I developed AI360, an enterprise platform combining natural-language-to-SQL and RAG search across structured and unstructured data. I built a multi-agent orchestration layer to route queries between its RAG and SQL agents.

I designed hybrid retrieval with semantic search, BM25, and reranking, and implemented answer validation and explainability. I also deployed the React and FastAPI application on GCP Compute Engine.

On FinanceBot, I developed an NL-to-SQL system using retrieval-based prompting, metadata-driven SQL generation, and conversational memory. My independent projects include a platform for comparing healthcare regulatory documents and a RAG chatbot and knowledge assistant.
