You will get AI chatbot with RAG using your data (GPT, LangChain)
Top Rated
Project details
I will build a custom AI chatbot powered by RAG (Retrieval-Augmented Generation) that uses your data to deliver accurate, context-aware responses.
Unlike basic chatbots, this system retrieves information from your documents, website, PDFs, or database and generates intelligent answers in real-time.
What I deliver?
• AI chatbot trained on your data (PDFs, docs, website, APIs)
• RAG pipeline with vector database (Qdrant, Chroma, etc.)
• Fast semantic search + accurate responses
• Clean UI or API integration for your app/website
• Memory support (optional) for better conversations
• Scalable architecture using LangChain / LangGraph
Use cases:
• Customer support automation
• Internal knowledge assistant
• AI FAQ or helpdesk system
• SaaS AI features
Tech stack:
OpenAI / Claude / Gemini, LangChain, Vector DBs, Node.js / Python
I build production-ready systems, not demos. Clean code, scalable design, and full deployment support included.
Send me your use case and data, and I’ll propose the best architecture.
Feel free to have a quick meeting before purchasing the project if you have any specific requirements.

I build scalable SaaS platforms, enterprise dashboards, and AI-powered products using React, Next.js, Node.js, and Python with deep expertise in LangChain, RAG pipelines, vector search, and autonomous AI agents.
What I Build:
→SaaS Platforms & Web Applications
Full-stack development with React, Next.js, TypeScript on the frontend and Node.js, Express.js, or NestJS on the backend. Clean architecture, responsive UI with Tailwind CSS, and scalable REST API design.
→ AI Agents & LLM-Powered Systems
Production-grade AI applications not just prototypes. I design and deploy RAG systems, semantic search engines, agentic workflows, and AI automation pipelines using LangChain, LangGraph, and OpenAI/Claude/Gemini APIs.
→ AI Workflow Automation (n8n, GoHighLevel, Python)
I connect AI and your existing tools into automated workflows that remove manual work, lead routing, follow-ups, data sync, reporting, CRM automation. Hands-on with n8n, GoHighLevel (GHL), Zapier-style logic, and custom Python automation.
→ Custom Model Deployment
Experience hosting and serving open-source LLMs (LLaMA, Mistral) on RunPod, Ollama, and vLLM infrastructure. Fine-tuning and deploying custom models for domain-specific tasks including reranking and embeddings (Nomic).
Tech Stack:
