About this gig

Want an AI assistant that answers from your own documents, or an AI agent that completes real tasks in your tools? I build RAG and LLM applications in Python that are grounded in your data and ready to plug into your product.


What I can build:

  • RAG chatbots over PDFs, docs, websites, Notion, or databases
  • LLM apps with a FastAPI backend and a simple chat UI
  • Tool-using AI agents with LangChain, LangGraph, or CrewAI
  • Multi-agent workflows for research, support, or data processing
  • OpenAI, Claude, or open-source LLM integration into your app

What you receive:

  • Working application and full Python source code
  • Document ingestion, embeddings, and a vector database set up
  • Prompting and retrieval tuned to cite your sources
  • Setup guide, plus deployment to AWS or your server on Premium

How it works:

  1. Share your use case and sample data
  2. I propose the architecture and scope
  3. I build, test on your real questions, and iterate
  4. You get the code, a demo, and a handover

Ideal for SaaS founders, startups, and teams who need a knowledge assistant or an AI feature built properly, not a demo that breaks.
