I once deployed a small service in 2016. It was a sort of configurable API, that other companies could post information to. Every company’s information came in a different json structure, but I built the thing to be able to accept a new structure, with new configuration data (no new coding needed for new formats).

Then in 2019, I was interviewing for a job and they asked me to talk about something I’d built that was reliable and I was able to report that this little service, running in docker compose, had been up continually for the last two years with zero errors.

I remember installing Uhuntu back in 2012 as middle schooler, and never encountering any error at all.
