Architecture

Most architectural problems don’t arrive as crises. They arrive as tickets that take three times as long as they should. As estimates that are always off. As the quiet frustration of engineers who can see how it should be built — but never get the space to build it that way.

These series look at why that happens, and what the shape of a system actually costs in practice.

Refactoring

Refactoring is not about clean code for its own sake. It’s about the cost of every change that follows. This series looks at how tight coupling, missing tests, and accumulated shortcuts quietly make every feature slower — and how to make the case for fixing it.
