About this gig

Looking to build a powerful AI chatbot using LangChain, RAG, and OpenAI GPT-4?

I specialize in developing custom AI chatbots and AI web applications using Retrieval-Augmented Generation (RAG) architecture. Whether you need a knowledge base chatbot, document AI assistant, or enterprise AI solution, I will build a scalable and production-ready system tailored to your business.

What I Can Build:

  • Custom AI chatbot using OpenAI (GPT-4 / GPT-4o)
  • RAG chatbot with vector database (FAISS / Pinecone)
  • Document-based chatbot (PDF, DOCX, CSV, Excel)
  • AI assistant for websites or SaaS platforms
  • AI automation tools for businesses
  • Backend APIs using FastAPI
  • AI integration into existing applications

Tech Stack:

  • Python
  • LangChain , Langgraph , Autogen , Google ADK
  • OpenAI API , Gemini API , AWS Bedrock
  • RAG Architecture
  • Vector Databases (Pinecone , chroma db , FAISS , Weeviate )
  • FastAPI , Django (RBAC)
  • SQL Databases

I focus on building secure, scalable, and production-ready AI systems, not just simple chatbot scripts.
