I will build a custom rag pipeline and ai agent with fastapi and pgvector


About this gig
Are you looking to integrate custom data into Large Language Models (LLMs) with high precision and low latency?
I build robust, production-ready Retrieval-Augmented Generation (RAG) systems and Agentic AI workflows tailored for your business needs.
What I Offer:
- Custom RAG Architecture: Document chunking, embedding generation (Cohere, OpenAI, Jina), and vector storage.
- Vector Databases: PostgreSQL (pgvector), Pinecone, or Qdrant integration.
- Hybrid Search: Dense + Sparse search for maximum retrieval accuracy.
- Backend Integration: High-performance REST APIs built with Python & FastAPI.
- Autonomous AI Agents: LangGraph workflows for complex, multi-step tasks.
- Clean Code & Docs: Fully typed (Pydantic), documented, and Dockerized code.
Tech Stack:
Python | FastAPI | PostgreSQL / pgvector | LangChain / LangGraph | Docker | OpenAI / Cohere
How We Work:
1. Contact me with your requirements before placing an order.
2. We define the project scope, tech stack, and deliverables.
3. I build, test, and deliver the system with step-by-step instructions.
Let's turn your data into an intelligent AI system. Send me a message to get started!

FAQ
Can you deploy the RAG system to my server?
Yes, I provide Dockerized setups and deployment guides for cloud platforms like AWS, DigitalOcean, or Hetzner.
Do I need my own API keys?
Yes, you will need your own API keys for LLM services (e.g., OpenAI, Cohere, Anthropic). I can guide you through setting them up.
