I run a Shopify store that relies on several third-party apps, and I need the entire site to feel as snappy as it looks. The goal is simple: every page—desktop and mobile—must load in under four seconds. To get there, I want all JavaScript and CSS files fully minified and compressed, any inline styles or deprecated HTML stripped out, and proper lazy-loading plus long-term caching applied to every image. I’m not looking for design changes; I just need cleaner, faster code while keeping all current app functionality intact. You’ll receive my current Google PageSpeed Insights and GTmetrix scores at kickoff. Once finished, hand back fresh reports from both tools so we can see the side-by-side improvement. Deliverables: • Optimised Shopify theme/code that consistently loads in <4 s • Minified & compressed JS/CSS pushed live • Inline styles and outdated HTML removed without layout breaks • Image lazy-loading and caching configured • Before/after PageSpeed Insights & GTmetrix reports confirming gains Acceptance criterion: every tested page meets the four-second target and passes Core Web Vitals.
