Debye Leong

UX Systems Architect & Front-end Engineer

Building accessible, scalable front-end systems for complex product environments.

I work by connecting structure, experience, and implementation — looking for the risks that usually hide between design intent, code, accessibility, and team assumptions.

How I Work

I use AI as a tool for reflection, reframing, and systems analysis: to challenge assumptions, stress-test decisions, and strengthen judgment rather than outsource it.

Systems

I look past demo-ready surfaces to find gaps in structure, consistency, and maintainability.

Experience

I work across front-end, UX, and accessibility to make products hold up in real use.

Judgment

I use AI to test assumptions and surface risks early, without outsourcing decisions or accountability.
