About this gig
Bring the power of AI to your project!
Are you looking to integrate GPT-4, Claude, or Llama into your application? I am a Python expert specializing in LangChain and LLM solutions. I help businesses automate tasks and analyze data using state-of-the-art AI.
What I offer:
- Custom Prompt Engineering: Getting the best results from LLMs.
- RAG (Retrieval-Augmented Generation): Let the AI "read" your documents and answer questions accurately.
- LangChain Chains: Building logical sequences for complex AI tasks.
- Vector Database Integration: Pinecone, ChromaDB, or FAISS setup.
- API Integration: Connecting AI logic to your existing backend.
Why me?
I have commercial experience managing LLM solutions and building scalable backends. I don't just write scripts; I build production-ready AI components.
