First I lived it.Then I built it.

Ten years entering data, checking it and explaining the numbers. Today I build the systems I wish I had back then.

I build for the people using it.

Real operations never look like the diagram. I start with the people: what they do, where they get stuck and what they need to keep going.

The system should fit the work. People should not have to do the opposite.

Ten years working with operational data and seventeen in tourism. That experience taught me to build around the people who use the system.
