I am more of a backend developer than a frontend developer. However, an app is useless to end-users without a front end. If I have to code the frontend side, I will choose React or Next.js. For the backend, I used Django, Flask, ExpressJS, or Golang.

I also know how to set up CI/CD and provision infrastructure using Terraform. Your app will have automated tests and continuous integration/delivery with GitHub Actions, CircleCI, BitBucket Pipelines, or GitLab Ci/CD. Your data will have automatic backup and be guaranteed to be restored when needed. Your app will be easily moved to different cloud providers. You can also experiment with deploying your app to multiple providers to compare its costs. Your app will also automatically scale when the number of app users grows.
