Membership site and API's Using NestJS

Description

Hello,
What I am looking to have developed is a membership site for my users. That will have the normal login and register operations, user back offices, payment integration for purchasing memberships. As well as add on purchases from the members area. I need a secure platform that cannot be hacked/exploited.
I also need to have api's created, and interact with some other api data from another company that I will be using to pull data into my back office for users. And save and sort that data into my own database that will need to be very agile.
I want to use Atlas for the databaseI want to use NEXTJs & NestJS
If you are an expert in NEXTJs & NestJS and know about Atlas let me know if you are available for this and that you can accomplish deploying to serverless at scale
Thank you
