Looks Like This Service Is On Hold
I will build a custom ai chatbot or agent using python and langchain
Danish Sethi
About this gig
Are you looking for a custom AI chatbot or intelligent agent built with real engineering, not a no-code drag-and-drop tool?
I build production-ready AI chatbots and autonomous agents using Python, FastAPI, LangChain, and LangGraph. Whether you need a customer support bot, an internal knowledge assistant, or a fully autonomous AI agent with tool use and memory, I deliver clean, deployable code that actually works in production.
What you get:
- Custom AI chatbot or agent tailored to your use case
- RAG pipeline over your documents, databases, or APIs
- REST API endpoints ready to integrate anywhere
- Deployed on GCP Cloud Run, AWS, or your infrastructure
- Full source code + documentation
- Post-delivery support
Tech stack: Python, FastAPI, LangChain, LangGraph, Vertex AI, OpenAI, PostgreSQL, Redis, GCP
Why work with me?
I've built and shipped 7+ production AI products across immigration tech, fintech, voice AI, and web auditing. Every deliverable undergoes a strict QA review before shipping; nothing ships unless it's production-ready.
Message me before ordering so I can properly scope your project and recommend the right package. I reply within 1 hour.
