03 / principlesRead before writing.
The code, the people, the constraints. We learn how your system works before deciding what needs to change.
Earn the complexity.
Start with the simplest design that meets the requirements. Reach for something clever when the evidence calls for it.
Make it maintainable.
Meaningful tests, observable behaviour, and clear decisions. Leave the next engineer a system they can understand.
