For ten years I've built web apps end to end — database, backend, and the interface down to the last pixel. What I care about isn't the 'full-stack' label; it's whether the thing still works once real users show up. Lately that whole thing increasingly gets built with a fleet of AI agents: they write and review, I coordinate, keep watch and answer for what reaches the client. The rest hasn't changed: it has to hold up under real traffic, and the client should know where things stand before they have to ask.
