We need a single page website with user login/registration using mobile/email otp, a subscription based website to display some restricted dashboard (already built using python dash ) the dashboard content needs to be based on user subscription, for reference boilerplate is provided here. https://easysaasboilerplate.com

We will prefer addition Indian payment gateway i.e. https://razorpay.com/docs/payment-gateway/server-integration/python/test-app/ to be added in subscription payment. Will prefer this to be deployed on AWS.
