1. Ai Ml Engineer

   Architected an asynchronous multi-agent system with FastAPI, LangGraph, and Snowflake for analytics and document intelligence- Designed an orchestration framework with LangGraph, combining subgraphs for database, document, and web retrieval into a unified state-machine. Implemented conditional routing, parallel execution, and a broker mechanism to merge results into a single response- Developed a database agent that converts natural language questions into optimized Snowflake SQL, executes queries, and summarizes results into clear business insights. Improved query accuracy by 30% using FAISS-based schema retrieval, sqlglot validation, and self-correction loops- Built a document agent powered by agentic RAG with Qdrant, applying a “planner–worker” design: complex questions were decomposed into sub-queries, retrieved in parallel with category-aware filtering, answered with contextual LLM calls, and stitched into comprehensive reports with citations- Implemented buffer memory, caching strategies, and error-handling loops to enable context-aware multi-turn interactions, reduce redundant LLM calls, improve scalability, and ensure robust performance under real-world conditions- Exposed the entire LangGraph orchestration as an async FastAPI endpoint, delivering high-throughput, low-latency workflows across SQL and agentic RAG pipelines.
