About this gig

Need a custom AI chatbot that actually understands your business and delivers accurate responses?

I'm an AI Engineer and AI Researcher specializing in building intelligent chatbots powered by LLMs, RAG, and LangChain. Whether you need a customer support assistant, document chatbot, internal knowledge assistant, or a custom AI solution, I'll build a chatbot tailored to your requirements.

What I can build:

AI chatbots using GPT, Llama, Claude, Gemini, or other LLMs

RAG-based chatbots with document understanding and source citations

PDF, DOCX, TXT, and website knowledge integration

AI agents using LangGraph, AutoGen, or CrewAI (if required)

FastAPI/Flask backend APIs and database integration

Deployment support and complete source code

I focus on building scalable, well-documented, and production-ready solutions with clean code and clear communication throughout the project.

If you're unsure which approach is best for your project, feel free to send me a message. I'll review your requirements and recommend the most suitable solution before we get started.
