What I'm looking for

I'm looking to build production AI systems involving LLMs, RAG, intelligent agents, backend services, and end-to-end deployment workflows.

I'm building production LLM systems at Anuvadini AI, where I designed parent-child chunking that improved retrieval completeness by approximately 40% and deployed containerized FastAPI microservices on Azure for a chatbot platform serving five client sites.

I've also built a multi-tenant AI chatbot platform with FastAPI, LangGraph, Qdrant, PostgreSQL, and WebSockets, plus an autonomous research assistant that uses LangGraph and multiple search providers. My work spans RAG, hybrid search, reranking, vector databases, prompt engineering, offline model optimization, and end-to-end AI deployment.
