Speeding up CI/CD processes

Create a separate CI process only for the things which are not affecting functionality. Such as linters.

Use the exactly same package for prod deployment as for staging with proper config parameter.

Deploy first, then execute tests (or at least in parallel)

Execute the full build once a day or so, for monitoring

Add an additional requirement of PR: a report from the engineer which includes tests results, linters, etc...

Create a dashboard for periodic builds, so it's visible for everyone and everyone sees that there is a problem.

Use of feature flag for everything that we deliver, so things can be turned off whenever needed without affecting the user

Put the responsibility of code quality on the engineers

Execute the build only related to the changed of that build.

Within a separate steps of the build, combine the tasks that rely on the same preparation steps into one.

If a related test is failing, try to identify what feature was affected and how, and disable it temporarily until fixed.

Stop building all the sub projects together. We only need to build and check the sub-project that was affected
