Once upon a time, there was a young, clean-shaven dev.
Soon in his career the smooth faced dev realized he had a knack for cloud setup. He understood permissions and network configurations, he could tell apart security groups from access groups, he could get all the information needed for an IPSec VPN in a single breath.
But if things got really tough, if the network layout was really messy, if the security settings too arcane, some older, bearded senior dev would come to solve everything.
Time passed, the junior dev got better at stuff, switched companies many times, solved a million problems, delivered countless projects, attended infinite meetings - twice - and, as often is the case, the senior devs, one by one, left the companies and run ever more scarce each day.

One day, a long, loooong time after his first meeting, the once young dev was solving network problems. Weird ones. Tough security requirements. Poorly documented cloud services. For hours, the dev and his colleagues toiled away, chipping at the problem without getting at its core.
The silence fell in the meeting. Everybody looking at each other, waiting for someone to say something.
Then they all looked at the dev, their eyes crying for help.
And the dev realized that he hadn't shaved in weeks.

I've shaved since then.
And I did solve the problem. Took many more hours, though.
