The hero tech lead carries the product alone — until the day they take time off

The hero tech lead syndrome: how a managed squad dissolves bus factor

Every startup has one. The person who knows everything, decides everything, codes the critical part. When they go on vacation, engineering stops. A managed squad dissolves that bus factor by default — not by luck. See how and why it matters.

A pretty roadmap on a slide is easy to produce — the hard part is the software behind it actually working

Frost taking over a branch: the freeze starts slow, and almost nobody notices.

The stack you never update sends its bill without warning

I keep reviewing products running on versions that died years ago, and the pattern holds: nobody decides to freeze the stack, it freezes on its own because maintenance never fits into any budget.

The product is yours on paper. The key sometimes lives on another company's keyring.

Who actually owns your code? The answer is usually worse than you think

I watched a healthtech spend 23 days getting admin access to its own repository. On paper the code was theirs. In practice it was not. On the gap between owning something in a contract and owning it for real, and the half-hour test that shows which side you are on.
