About

AI Chatbot Developer Expert in LangChain, FastAPI, Python RAG, Vector DB, Voice AI Integration

I am Ritesh Shah, an AI developer specializing in intelligent chatbot development using cutting-edge technologies such as LangChain, FastAPI, and vector databases like Pinecone.

I've built production-ready RAG (Retrieval-Augmented Generation) chatbots that can read PDF documents, respond to user queries in real-time, and even handle memory-based conversations.

My expertise covers:

LangChain (chains, memory, retrievers, tools, agents)

FastAPI backend development (including Docker deployment)

Pinecone vector database and embeddings

OpenAI LLMs and prompt engineering

Frontend integration for chatbot upload and usage

Whisper & ElevenLabs for voice AI integration (currently learning)

I focus on delivering fully working, client-ready chatbot systems that can serve real estate businesses, customer support, education, healthcare, and more.

Currently, I'm building a strong portfolio and looking for meaningful freelance projects where I can apply my skills and grow.

Outside of work, I enjoy tech tutorials, learning about agentic AI, and helping small businesses implement AI solutions. Let's connect and build something impactful together!
