Abdul R.

I build AI-powered web applications using LLMs, LangChain, OpenAI API, RAG, and modern full-stack tools like Next.js, React, Node.js, and MongoDB. I help startups and businesses add practical AI features to their products, such as document-based chatbots, AI assistants, automated workflows, API-connected agents, and custom AI dashboards. My background as a full-stack MERN developer allows me to build not only the AI logic, but also the complete production-ready application around it. I can help with: - AI chatbots using your PDFs, documents, or website data - RAG systems with vector databases - LangChain / LangGraph-based AI agents - OpenAI, Claude, Gemini, or local LLM integrations - AI SaaS dashboards using Next.js and Node.js - Bug fixing and improvement of existing AI apps Tech stack: OpenAI API, LangChain, LangGraph, Pinecone, Chroma, FAISS, Supabase, PostgreSQL, MongoDB, Next.js, React, Node.js, Express, Python, FastAPI. If you need an AI feature that actually works inside a real web application, I can help you build it.
