About this gig

I will build a practical custom GPT or AI agent app for your business workflow.


I can help with:

- Custom GPT setup with files, instructions and conversation starters

- AI agent workflows using LangChain or LangGraph

- API actions for your backend, CRM, database or internal tools

- RAG-style knowledge search from docs, PDFs or website content

- Clean handoff docs so your team can maintain it


I have 13+ years of backend engineering experience and can connect AI features with real production systems, not just demos. Message me before ordering so I can confirm the scope, data source and best package.
