You will get Multi-modal RAG architect for enterprise AI systems (Pyhton + Langchain)
Project details
I design and build production-grade AI systems that unify private documents, structured data, and live information into scalable RAG-based architectures.
My focus is not on prototypes; it’s reliable AI infrastructure that performs under real production constraints: latency, retrieval quality, scalability, and maintainability.
WHAT I BUILD
Enterprise RAG systems for document + live data intelligence
Multi-modal pipelines (text, audio, embeddings, APIs)
LLM-powered agents using LangChain & LangGraph
Vector search systems (Qdrant, Weaviate, etc.)
Local + cloud LLM deployments (BentoML, Ollama, OpenAI, Cohere)
CORE STRENGTH
I don’t just integrate models; I design end-to-end retrieval systems that are measurable, scalable, and production-ready.
