UX Engineering

The UI holds up across devices and users: accessible, adaptive, and built as a system, not a pile of screens.

How it works

A left-to-right map of the work. Ports stay on fixed sides so the edges do not cross more than they have to. Pan or pinch if you want a closer look.

The usual problem

  • A multi-step flow hides status, so users cannot tell where they are.
  • Contrast and tap targets fail the people who need the product most.
  • Each brand or device gets a one-off layout instead of a system.

How I approach it

  • Accessibility and contrast are part of the widget system, not a pass at the end.
  • Layouts adapt. They do not shrink.
  • Reusable widgets beat a new screen for every state.

Process

  1. 01

    Journey

    The flow the user is actually in, including where they stand.

  2. 02

    System

    Accessible, adaptive widgets that can be reused.

  3. 03

    Brand

    Flavor theming where one codebase ships more than one face.

  4. 04

    Handover

    The widget system and the rules for adding a screen.

What you get

  • The widget system
  • Adaptive layouts that hold on small and large devices
  • Theming rules when more than one brand ships from the same code

How risk stays down

  • Status is visible. Users do not guess which step they are on.
  • Contrast and targets are designed, not patched after a review.
