You will get a custom Generative AI chatbot that answers using your data
Project details
Build a custom AI chatbot tailored to your business using OpenAI, Retrieval-Augmented Generation (RAG), and LangChain.
I develop AI-powered chatbots that can answer questions, retrieve information from your documents, and integrate with your existing workflows. Whether you need a customer support chatbot, an internal knowledge assistant, or a custom AI solution, I focus on building reliable, scalable, and maintainable applications.
My solutions can include OpenAI integration, LangChain pipelines, vector database support, FastAPI backend development, prompt engineering, and document-based knowledge retrieval. I write clean, well-structured code and provide clear communication throughout the project.
Every project is built around your specific requirements rather than using a one-size-fits-all template. If you're looking for a practical AI chatbot that delivers real business value, I'd be happy to help.

About Md. Mehadi
AI Chatbot & Agent Developer | RAG, LangChain, FastAPI, OpenAI API
Sirajganj, Bangladesh - 1:06 am local time
I help startups, founders, and businesses build AI-powered solutions that go beyond simple chatbots. My focus is on developing AI chatbots, AI agents, RAG-based applications, custom AI assistants, and scalable backend APIs that integrate with modern LLMs and business workflows.
My technical stack includes Python, FastAPI, LangChain, LangGraph, OpenAI, LlamaIndex, ChromaDB, Pinecone, Weaviate, SQL, MongoDB, Docker, Git, and REST APIs. I also work with Retrieval-Augmented Generation (RAG), vector databases, prompt engineering, AI workflow automation, and Model Context Protocol (MCP) for building reliable AI systems.
Although I am at the beginning of my freelance journey, I have invested significant time building personal and portfolio projects to strengthen my practical skills. Every project focuses on writing clean, maintainable code, creating scalable architectures, and solving real business problems with AI.
I can help you with:
• AI Chatbots powered by OpenAI and RAG
• AI Agents using LangGraph and modern agent frameworks
• FastAPI backend development for AI applications
• OpenAI API integration and custom AI assistants
• LangChain and LlamaIndex applications
• Vector database integration (ChromaDB, Pinecone, Weaviate)
• AI workflow automation and backend APIs
I value clear communication, honest collaboration, and long-term client relationships. If you're looking for someone who is committed to delivering well-structured AI solutions and continuously improving with every project, I'd be happy to discuss how I can help.
