I worked at a place a few years ago that was still writing coldfusion apps. The apps worked fine, but they had a ton of trouble recruiting developers. I pitched switching to Spring Boot to greatly widen the talent pool and was accused of trying to bolster my own resume. Now, Spring Boot ain’t exactly the trendiest tech, but I was trying to make a good decision for the organization and, yes, also for my own resume. Often not mutually exclusive.
