  • Code splitting
  • Minification + compression
  • Defer / async scripts
  • Lazy loading
  • Image optimization via Shopify CDN
• Maintain a clean, version‑controlled deployment workflow.

• Improve ATC rate, product discovery, clarity, and mobile usability.
• Implement A / B testing variants from the CRO team or propose your own.

• Configure and maintain GA4 event tracking (ATC, IC, upsells, search behavior, scroll depth, etc.).
• Set up session recording and heatmaps (Hotjar or Clarity).
• Interpret funnels with the team and provide actionable recommendations.

• Weekly updates on:
  • Conversion rate trends
  • AOV impacts
  • Funnel drop‑off changes
  • Site issues or speed regressions
• Maintain clear documentation and async communication with product, ops, and design.

• 3+ years building custom Shopify themes (Liquid, JSON, JS, CSS, Shopify APIs).
• Proven results improving mobile conversion and checkout / speed performance.
• Hands‑on experience with Dawn / OS 2.0 custom theme development.
• Strong frontend fundamentals : modular Liquid architecture, performance‑first coding, clean components.
• Deep Shopify optimization skills : theme speed improvements, app performance audits, and custom replacements for heavy apps.
• Experience working with high‑volume DTC brands.

• Experience with CRO tools (Rebuy, Bundler, Zipify, Okendo, Stamped).
• GA4 modeling, attribution & Shopify Pixel system.
• Headless / Hydrogen experience.
• Hotjar / Clarity usage for experience analysis.
• Familiarity with Klaviyo event triggers.
• Experience partnering with CRO strategists, designers, or A / B testing teams.
