Building a design system
while the product is still finding its shape
UX Engineer
Designing and building interfaces where research, usability, and craft meet.
I'm Mandy Hartman, a UX engineer who works across research, interaction design, and front-end implementation — turning fuzzy product problems into clear, shippable experiences.
Specialty
Design systems, prototyping, accessibility, React, and end-to-end product work.
Field Notes
I write about the overlap of UX and engineering: how research informs build decisions, what makes design systems stick, and where the details of an interface change how people feel using it.
