Must‑Have Skills

  • Advanced HTML/CSS/SCSS + modern JS (ES6+).

Experience cutting CWV on live sites (share metrics).

CRO awareness (placement of CTAs, F‑pattern, etc.).

Familiarity with PageSpeed Insights and Lighthouse.

Proposal Checklist – Keep it Short

  • 2–3 live URLs you improved (no screenshots).
  • One‑paragraph plan for hitting CWV & launching safely.

Timeline in calendar weeks (≤ 4 weeks).

Confirm: weekly 30‑min check‑in (Mon–Thu, 9 – 12 pm PT) + NDA.
