A bit about me

I'm a front end engineer with over 15 years of experience building interfaces that balance clarity with complexity. I gravitate toward projects where the UI has real work to do — turning dense data into something a person can actually act on.

My career has taken me from agency work at Fusion92 to building AI-powered dashboards at Orgaimi. Whatever the context, my instinct is the same: find the simplest path to the clearest picture.
