Definitely, I was a college professor through my mid-30s. I spent 3 years as a stay at home father, and then built an iOS app startup. The startup wasn't quite financially sustaining, but I bootstrapped my iOS app work to become a professional software engineer just as I was reaching 40. I developed in the Apple ecosystem for about 5 years and then migrated to cloud services. I am now a data engineer and very happy and fortunate to work for an enthusiastically Clojure-friendly company.
