Certified Pharmacy Technician up until 2015; now a Senior Software Developer at the most well-known healthcare insurance provider in the United States.
At my position I have -- and still do -- practice nearly all of my life knowledge of technology: from Linux administration to software development; from IT security to [scientifically-practiced] troubleshooting; Kubernetes to Pega; and far beyond.
The experience and expertise I can provide will benefit all Stack Exchange users; and if it doesn't, then chances are I'll learn something new. And no matter who you are, we all still have something new to learn, so I try to embrace being wrong -- you should too! At least then it'll mean you're that much less likely to be wrong next time!
