I had all the AWS certs and I can say it's a total waste of time. These certifications (AWS) probably is for sale engineer than a engineer that really do the works. But I had to get the certs in order to become an AWS partner :(.
When you say you had "all the AWS certs", which ones specifically? I've worked with AWS for a couple of years now, and most of my knowledge has been gained as I have needed to solve certain problems. I'm in the process of studying for some of the certs.
Still, I find the AWS ecosystem is so vast, and I certainly have gaps in my knowledge. The process of studying for the certs has forced me to approach AWS with a more academic lense, learning some things that I may have not known otherwise.
I can't help but feel like some of these bits of information ultimately give me more context, and may even make me more effective on the platform.
