Senior AI & LLM Engineer building production RAG, intelligent automation, and scalable full-stack systems.

What I'm looking for

I’m looking to build and deploy production LLM/RAG systems and intelligent automation that improve real product workflows—working with strong engineering teams on scalable architecture, rigorous testing, and modern AWS-based delivery.

I’m a Senior AI & LLM Engineer with over 10 years of experience building scalable full stack systems and intelligent applications using Python and Java. I focus on production AI solutions—especially large language model integrations, retrieval-based systems, and intelligent automation that strengthen product capabilities and data-driven workflows.

At Capital One, I built enterprise AI knowledge retrieval platforms using Python, LangChain, and RAG that analyze 10K+ internal documents and generate contextual responses through AI assistants and conversational interfaces. I also developed scalable LLM orchestration services with FastAPI and LangChain (prompt engineering, few-shot prompting, and context window tuning), implemented AI agents and multi-agent workflows with AutoGen and CrewAI, and delivered semantic search with vector embeddings using FAISS and Pinecone—while integrating LLM APIs across OpenAI, Anthropic Claude, and Hugging Face Transformers and deploying production AI on AWS at 100K+ AI queries per month.
