Hey there,
Hope you are doing well. I can see that you are looking for a person who can completely meet your project criteria. I would like to let you know that I have understood everything and find myself perfect for this project. I will be doing it under your calculated budget and timeline.
Looking forward to your response.
Thanks
I think you are writing code to show error if we input wrong card details. We have to enter only one line for error handling at the end of the payment from container in the frontend. I recently worked in a stripe payment process project. I will host your stripe backend in heroku if you need.
