    Ehtesham is a skilled full stack developer who delivered the setup for my AI healthcare web app quickly. He handled the front end development in Next.js/React and the FastAPI backend, and planned the AI/RAG integration well. If you need someone to build an AI website or handle web app development, I’d recommend him. Great communication and on-time delivery
