Salute to you. I wrote my first code the year the author of the article was born, on an HP-3000 using a teletype :). I'll be 60 next year, and currently work as a sr. devops engineer building infrastructure and toolchains on google cloud platform/GKE. It's a great gift to be able to do something you love to put food on the table, and to be able to keep doing it as long as the brain is up to the task.
I started professionally as a c++ programmer, and have worked in a few different languages, on a few different platforms since. This job is my first devops position and I wasn't actually looking for devops roles when it was offered to me. I was interviewing for a back end engineering position and the head of the devops/SRE group saw some things in my profile that he was looking for and reached out. Fwiw I'm almost through the "after 50" part and getting close to the "after 60" part and I haven't had a problem finding things to do. The key is to stay engaged and learning all the time.
great info thanks, happy to see that people like you, who are not afraid to learn new stuff and integrate that into their long experience is still valuated.
