07 / 10Product Engineering

The same holiday-rental app on a desktop display, a tablet and a phone. The desktop shows a six-listing grid beside a map, the tablet a two-column grid, and the phone a single column with a tab bar. Saving the first listing on one device saves it on all three.

Built to feel right on every screen.

Great apps happen when design and engineering work as one: interfaces that look considered, load fast, adapt to any screen and keep holding up as the product grows.

Design system

Components first. Screens follow.

  1. A type scale with clear roles, so hierarchy reads the same on every screen.

  2. Primary, secondary and quiet actions, with hover, pressed, loading and disabled states.

  3. Fields, toggles and pickers with labels, focus rings and helpful errors built in.

  4. One card anatomy (media, title, meta, action) reused across lists, grids and search.

  5. Top bars on wide screens, tab bars on phones: the same destinations, arranged for the device.

  6. Date pickers, toasts, steppers and sheets, composed from the pieces above.

Performance

Fast is a feature.

We set performance budgets early and check them on every release, on mid-range phones as well as fast laptops.

Fast loading

Pages render on the server, images arrive sized for the screen and code loads only when it’s needed, so the main content appears in well under a second.

  • Server rendering
  • Responsive images
  • Code splitting

Optimized rendering

Long lists stay smooth, animations run on the compositor and nothing jumps around while it loads.

  • Virtualised lists
  • GPU-friendly motion
  • No layout shift

Responsive interaction

Every tap gets instant feedback. Heavy work moves off the main thread, so the interface answers before the network does.

  • Optimistic updates
  • Work off the main thread
  • Instant feedback

Accessibility

Readable contrast, visible focus, generous tap targets and real labels, designed in rather than patched on later.

  • WCAG 2.2 AA
  • Keyboard & screen readers
  • Reduced motion

SEO

Server-rendered pages, clean URLs and structured data give search engines what they need, and give your pages rich results.

  • Structured data
  • Metadata & sitemaps
  • Core Web Vitals

One experience

Designed once. Experienced everywhere.

One design system and one set of APIs behind every screen, so the product feels like itself wherever people pick it up.

Next step
