What I'm looking for

I want to build scalable, production-grade agentic AI and RAG systems—integrating LLMs, hybrid retrieval, and FastAPI services—while continuously improving performance through evaluation/testing and production-ready deployment workflows.

I’m an Agentic AI Engineer with 2+ years of experience designing and developing Generative AI and Agentic AI applications. I focus on building AI agents, multi-agent systems, and Retrieval-Augmented Generation (RAG) solutions that deliver accurate, context-aware responses.

In my current role, I developed a production-ready RAG Knowledge Assistant using LangChain/LCEL, ChromaDB, BM25, and HuggingFace embeddings. I integrate OpenAI/Groq LLMs with custom prompt templates and streaming responses, build FastAPI REST APIs for document upload/indexing/question answering, and use evaluation/testing workflows to monitor retrieval quality and LLM response accuracy—so the systems are scalable and production-grade.
