Hey! I'm Ayush, a full-stack developer and AI agent developer who loves building projects based on real-life issues. I enjoy taking ideas from a blank canvas to production, whether it's a modern web application, an AI-powered workflow, or an intelligent automation system.

Building with Next.js, React, Node.js, Express, MongoDB, TypeScript, and the MERN stack, while pioneering Generative AI, LLMs, LangChain, LangGraph, and autonomous Agentic AI architectures.
