About this gig

I build custom AI agents and RAG chatbots using Python, LangGraph, LangChain, vector databases, and leading LLM APIs.

I can develop document-based chatbots, multi-step AI workflows, tool-using agents, memory-enabled assistants, API integrations, and human-in-the-loop systems. My focus is on practical, maintainable solutions rather than basic template chatbots.

Depending on the selected package, your project may include document retrieval, conversation memory, database integration, external tools or APIs, testing, source code, setup instructions, and deployment assistance.

My experience includes building a LangGraph email agent with contextual memory and human approval, conversational AI workflows, production Python systems, and machine-learning pipelines used for fraud detection and scientific research.

Please contact me before ordering so I can review your requirements, confirm feasibility, and recommend the correct package.


Important: hosting costs, paid APIs, model usage, cloud services, and third-party subscriptions are not included unless explicitly agreed.
