mobile first design of a subscription page with email verification

What are you most proud of, and what would you do differently next time?

i am proud of using sass preprocessor for the frontend part and using nodejs and express for creating the server file for managing the backend which is capable of sending an email to any valid gmail address.

What challenges did you encounter, and how did you overcome them?

faced some problem in writing the backend code but it was resolved later

What specific areas of your project would you like help with?

i want to make my local server public so that the backend part could be run successfully by using other devices too , but am facing some problems currently to perform this task.

Any advice will be highly appreciated.
