AboutI'm interested in what happens when technology changes the way we build, think and grow.
I build, experiment, study and document what I learn along the way. Most of it starts as a question I can't answer by reading, so I build the smallest version of it and watch what happens.

What I learned, written down.

The quiet cost of every feature you keep.
Removal is a feature. It is just harder to put on a roadmap.

What a forecasting model taught me about trust.
People do not adopt accuracy. They adopt something they can explain to someone else.
Growth02 Jul 20264 min
Distribution is a product decision.
If nobody can carry it to the next person, it is not finished.
