My first "software engineering" scale project was working on a existing massive 10 y.o js pub/sub and java templated webapp. Taught me why typed languages are valuable, why I should never listen to PMs, why I should be humble, why estimates are impossible but sort of important, and why long feedback loops anywhere in the entire process (including compilation) are productivity killers, along with not having an isolated private work area.
