As a senior SWE at Amazon I had the autonomy to do this sort of thing as soon as the several years worth of work my team had planned was done. Half the senior SWEs at a big job board that calls itself a tech company are concerned with migrating everything to per-table microservices that expose endpoints that do exactly the SQL queries other services used to do directly. Thanks for your report of your different experience in a different org. I'll try not to give people a false impression by posting about mine.
