Another thing here is that often times people are so busy "developing" product that really trivial efficiency gains get overlooked. Things like simply removing unnecessary parts from the build at least when you're testing / in dev mode. Also compartmentalizing the build to the portion of the app you're working on, ensuring it's not building the entire app when you're only testing one feature (you'll be surprised how common this is even especially at large companies). It's a huge value add to the rest of your team to bite the bullet and take an hour or so to shave off some minutes from the time you have to wait for a build. That one hour saves you from many multiples more (hours / days / weeks) of fiddling your thumbs in the breakroom waiting for a build to finish. (better yet to have someone regularly scanning for these efficiency related things)
