As a developer I've had some very good and very bad experiences... usually centered around two issues.. 1. I am not a morning person and am consistently late, I get work done, but not at 8/9am on the dot. And, 2. because I will take the time to understand what I am working on... this usually results in some refactoring and generally less code in the end. I once saved enough code in size to include lodash, and eventemitter into the client side of a project, by refactoring out a piece using those two libraries. I was of course chastised because it took longer than expected. I left when the writing on the wall was I would be fired anyway... That was over a year ago, and my understanding is the project I was working on with a 3 month delivery time still isn't done because no effort was made to resolve technical debt and they kept throwing more people/teams at it.
