How I work
A good interface goes beyond the visual layer.
I come from a systems background and work in frontend. That combination makes me look at each project through both the user experience and the resilience of everything behind it.
Clarity
Every element should help people understand, decide or move forward.
Performance
An interface is also designed to load and respond quickly.
Resilience
Accessibility, maintainability and security from the start.
