For me, it was during an on-going incident in a failing IoT OTA service which was growing in priority; taking two items I was unfamiliar with and bolting together new OTA mechanism via alternative SMS provider. I'd never developed in .NET ecosystem before and happened to gain access to another team's Twilio account in a prior week, so took a shot, planned interfaces to extract and implemented alternative Twilio implementation + feature flag

Normal software instincts plus access to a different service flushed the buildup of OTA's and lives on as a fallback mechanism. Amazed me going from idea to execution faster than I could have ever dreamed of even on-boarding myself to the area or environment.
