Few months ago I was working on something rhat wasn't mission critical for the current sprint. Near the end of the month I was asked to help the BD team (which usually do the testing) with testing the webapp as well as the mobile versions. First day of me testing ever, found more bugs by myself than the 5 BD people did in the entire week. Really felt like a boss. Next month they asked me to help again. And again. And again.
This is how my desk looks nowdays (the 3 phones are behind the laptop charging)
