As a team lead, my project sees them about once a quarter. This is on a project that fundamentally does form based data collection on a limited set of users.
The most recent one was where a dev used an array scan to find a piece of data in a record array. We changed that to a hash table look up and saw a 100-1000x increase in performance on our larger datasets.
Not quite as dramatic, but still pretty good.
If you aren’t producing single person solutions and your product doesn’t have any performance issues, you can either count yourself lucky to be working with great engineers.
