Is it really needed to have 40 microservices for 40 devs? What I mean is that you generally scale out to so many services when you need each to have variable scalability, so each part of the system can scale up/down as necessary.

If you don't need this, all these services could be written as larger modules, with proper separation of concerns but easy to be deployed as a single piece. Collect some stuff that are similar in domain and create a well designed monolith. Easier for operations, easier for devs to maintain. Dependencies upgrades aren't a nightmare, or you need very good tooling to not create toil (which generally a small operation won't have).

Just throwing this in the wind because it sounds pretty heavy for a 40-body shop to be carrying as many services, at least I don't see the benefits unless for the aforementioned scalability advantage.
