What I bring
I design for impact — products that solve real problems with measurable outcomes and driving engagement.
01
Research-led strategy
I turn user signals — interviews, analytics, support tickets — into product direction teams can actually ship. No design without evidence.
02
End-to-end product craft
Comfortable across the stack: discovery, IA, flows, UI, prototypes, and design systems. I move from messy problem to handed-off spec without dropping the user.
03
Accessible by default
WCAG 2.1 AA is the floor, not the ceiling. I design for keyboard-first, screen readers, and real-world conditions — and I bring that lens to every team I join.
04
Measurable outcomes
I tie design decisions to numbers stakeholders care about — engagement, completion, adoption — so the impact is visible long after the project ships.

Testimonials
What colleagues say
Kind words from the people I've worked with across enterprise, product, and non-profit teams.
“Chia single-handedly developed the initial brand and app design for our company, coming up with the concept for our logo alongside a clean and intuitive UI for our apps that perfectly captured our vision. Her creativity, speed, and ability to translate early startup gobbledygook into a streamlined design was really impressive.”
