I was fired by a client about a month back. I had spent about a year building a web application using angular.js for said client. Of course, it was my fault because it took about 8 months longer than I had forecasted but I believe what I was shooting for was something solid. I went as far as giving a full refund of the initial deposit on the project. My take away was I learned something new, going in I wasn't remotely aware of such things as CI/CD. Sad thing though they are trying to rebuild the app using wix.
