Early on in the company I work we had a practice of collaborating across teams, sharing members etc. so a lot of us knew a lot of the code base from "different angles". If you implemented a backend feature you might write also write the terraform and the frontend that worked with it, with some input from the people experienced in those things. Kind of like random full-stack development? Slower than normal development at first but it makes future collaboration easier. It was quite great, but unsustainable as the amount of people grows. edit: I think in general at the early stages of a company you hire a lot of people who are good at adapting and learning new skills since they might need to fill new roles quickly as new needs arise. So those people are good at this kind of full stack development since it's their niche. As you grow, you hire more specialized or junior people, and they can't do this process quickly enough for it to feel fluid anymore.
