I took the time to learn how to build and maintain Ruby on Rails systems, hoping it would be the ticket to a fun, manageable career. Any project I worked on was an island of sustainable, fast development where the team finished the sprint's work in a few days. I knew where the bottlenecks were should the project need to scale, and scaling issues never took down the site completely.
Only to throw all that expertise away when it was just decided to replatform one day. Because I guess stable just wasn't good enough. After it happened twice, well, might as well go into devops. Y'all are gonna need it.
