Performance‑Aware Design

We design UI and content with speed in mind: optimized images, semantic HTML, minimal code, and clear Core Web Vitals goals. Beautiful and fast.

StartWhat includes

Accents

Core Web Vitals

Clear goals for LCP, CLS, INP and TTFB.

Images without compromises

AVIF/WebP, art‑direction, adaptive sizes

Minimal code

Semantic HTML, reasonable CSS/JS, without bloat.

Default accessibility

Focus, contrast, ARIA, better UX and speed.

What you get

Design, specifications, and artifacts, with which you actually achieve fast pages.

Performance Design Spec

  • Goals: LCP/CLS/INP, resource budget (kB and requests)
  • Architecture: critical CSS, lazy‑load, defer/async
  • Semantics and ARIA, focus and skip‑links

Images & graphics

  • Art‑direction (picture/srcset/sizes), AVIF/WebP + fallback
  • SVG optimization and symbol sprites
  • Lazy‑loading and priorities for prefetch/preload

Components and templates

  • Responsive sections with fluid typography
  • Minimal dependencies, progressive enhancement
  • Examples for forms, navigation, modals without bloat

Monitoring & reports

  • Laboratory reports (Lighthouse) + field data (RUM)
  • Comparison before/after and prioritized recommendations
  • Regression test template

Process

We integrate performance into design and development—not as the last step, but in every phase.

  1. 1

    Base evaluation

    Analysis of current metrics and blockers.

  2. 2

    Design guidelines

    Mocks, tokens and components with performance rules.

  3. 3

    Build

    Clean HTML/CSS, minimal JS, QA matrix.

  4. 4

    Testing

    Lighthouse + RUM, real devices/networks.

  5. 5

    Launch & monitoring

    Field data, regressions and recommendations.

Goals and KPIs

Example values (we adapt according to the project and market).

  • LCP ≥ 2.5s (75-th percentile mobile)
  • CLS ≥ 0.1 on key pages
  • INP ≥ 200 ms
  • TTFB ≥ 0.8s (dynamic content)
  • Budget: ≥ 150kB critical resources
  • Lighthouse Performance ≥ 92

Packages

Start options; we scale according to your needs.
