03 / THE PERSON BEHIND THE PIXELS
Curious by nature.
Engineer by craft.
I care about the details you feel before you notice.
Perceived performance. Keyboard accessibility. The moment before the data arrives. I build interfaces that feel instant and hold up when real people use them.
These days, I build alongside AI agents: shaping the plan, directing the implementation, and owning the architecture, edge cases, and final review. A faster loop. The same high bar.
