Location: München, Germany

Budget: Recommended by industry experts

Time to start: As soon as possible

Project description:
"We urgently need a highly experienced Shopify performance optimization expert for our German medical supply website. Current PageSpeed scores are critically low—Mobile 40 and Desktop 60—and must be raised to Mobile 85+ and Desktop 85+ within just a few days.

Important: Functionality, design, and layout must remain 100% unchanged. The mission is pure performance optimization.

You will also receive a PDF outlining our proposed changes, but you are expected to independently analyze the site and identify further optimizations.

Critical issues to fix include:
- Render-blocking CSS files
- Unoptimized JavaScript execution
- Oversized, non-WebP images (conversion & lazy loading required)
- Weak Core Web Vitals performance

Required expertise:
- Knowledge of Shopify Liquid code
- Proven CSS/JS optimization skills
- Advanced image optimization (lazy loading)
- Strong technical SEO understanding

Notes: Image resizing within Shopify will be handled separately by us, so your focus remains on coding-level optimizations.

What you’ll get:
- Full theme files (no direct store access needed)
- Daily progress check-ins required
- Performance bonuses for surpassing targets
- Guaranteed ongoing projects for top-quality delivery

This is a mission-critical project for a professional site—success will lead to a long-term partnership with substantial future opportunities." (client-provided description)
