AI as a force multiplier
One person moving at this pace usually means AI is doing the work, so it is worth being plain about what it actually does here. It does the volume: the scaffolding, the repetitive passes, the second and third read over something I have already written. It does not make the decisions. What your site says, how it is put together and whether it is good enough to go live are mine, and they get checked against the written standard rather than against how I feel about it that afternoon.
The same method built the platform behind that portal, which is a considerably larger piece of software than any website. That is the honest test of whether it holds up: what used to take a team of ten and eighteen months of runway can now be built by one person who understands the problem properly. A website is the smallest version of that, and the easiest one to check, which is why the panel on the home page measures itself in front of you.
