I needed to transfer 100+ million rows from one database to another with some edits. I created script that restarts by cron from the previous stop
I needed to teach a person from zero to junior. I created study plan and mentored
Often I got tasks to optimize requests. I created profiler, searched slow (memory-intensive) parts of code and optimized it (from 4+Gb to 500Mb, from 3 sec to 0.1 sec)
We had a lot of requests to backend from managers who used many tabs in CRM. I synchronized data in several tabs to reduce the number of requests
Rarely bugs were reproduced only by clients. Then I called them and looked for bugs in our obfuscated code (js)
