You will get I Will Build a Custom RAG Pipeline with LangChain, OpenAI & Vector Database

Project details
I build custom RAG (Retrieval-Augmented Generation) pipelines using LangChain, OpenAI, and vector databases that allow your AI systems to understand and answer questions from your documents, databases, or other sources.
With expertise in Python, LangChain, OpenAI, and workflow automation, I design scalable, production-ready systems that work exactly how you need — no broken workflows, no incomplete projects.
Whether you want an AI-powered document assistant, internal knowledge base, or automated answer system, I deliver clean code, clear instructions, and thorough testing.
Services I Offer:
Custom RAG pipelines from PDFs, databases, and cloud storage
LangChain AI workflow development
OpenAI API integration (GPT-4, GPT-4o, Claude, Gemini)
Vector database setup (Pinecone, PostgreSQL, MongoDB)
Automation & workflow integration (n8n, Make, Zapier)
Smart AI agents and assistants
Bug fixing, optimization, and deployment support
