I have the opposite experience, the worst performance bottle necks I have had to trouble shoot are from principal engineers (and tech leads) that use medium to high level abstractions in a ruby on rails that don't actually understand what how many sql commands they are triggering by writing clever one liners that taco my db, from a rails 2.4 method that has a much better rails 5 system they don't know about.
