If everything is possible, why do we keep building the wrong thing?
Stop asking “what should we add next?” and start asking “what for?”, because every new feature brings new support… and sometimes it doesn't even bring real usage.

About · Human, mostly
Pragmatic
by design.
I'm Daniel, a senior software engineer in Spain. I treat architecture as a living system. I focus on how things communicate, change and fail without taking everything down.
Complexity needs an editor.
Reliable beats impressive.
Usage is the final test.
I write the software.
They run the household.
