I need a basic MVP web application where users can generate a t-shirt design using AI. Users should be able to enter a text prompt or optionally upload an image, see a simple mockup of the design on a t-shirt, and complete payment through Razorpay or Stripe. Admin access should allow viewing orders and downloading design files. This is a small MVP — no user login, no extra products, and manual order handling is fine. Focus on functionality, clean UI, and basic integration with AI APIs. Budget is ₹15k–₹20k, timeline 2–3 weeks. Please share examples of similar API-integrated projects you’ve built.
