Hire Whiley Mai Themes Experts

Speed & Performance Specialist for Shopify Stores

Your store is slow. I make it fast - and show you exactly how much revenue that speed costs you.

For 15+ years, I've optimized Shopify stores for businesses doing $500K+ monthly. I treat speed as a revenue problem, not just a technical checkbox.

Available Mon-Fri 7am-3pm EST. Flexible scheduling for urgent pre-launch issues.

Key Results:

• 7→65 mobile score for apparel brand, protecting $18K+ in Black Friday sales

• 74% faster load times across product pages and checkout

• 100+ projects delivered for brands in US, Canada, UK, and Australia

What I Fix:

• Slow product pages killing conversions

• Checkout delays causing cart abandonment

• App bloat dragging down performance

• Speed apps that didn't actually work

How I Work:

1. Diagnostic audit identifies actual bottlenecks (not guesswork)

2. Phased implementation - you approve each milestone

3. 90-day post-launch support

Best Fit: Stores doing $500K+ monthly where slow speed is actively costing conversions.
