    Great experience overall. The AI Agent POC was built cleanly with Python, LangChain/LangGraph, LLM integration, tool-calling logic, short-term memory, structured responses, and proper API testing support. Everything was easy to run and well explained.

    Abdul delivered a neat AI chatbot proof of concept with a simple web UI, FastAPI backend, and OpenAI API integration. The code was easy to follow, the setup instructions were clear, and the chatbot worked well for testing the basic conversation flow.
