the more i design/build, the more i realize: the wrong data structure is like a receding hairline. you're cooked. trying to cover it up makes it even worse spoke to other founders who agreed that data structure is the ceo's job. every engineer knows to avoid migrations when possible. an easy place to fuck ui is the account table. this takes scaled companies +6mo to fix. almost sure ramp/linear ship fast because they made fewer mistakes here.
