Zero Lifestyle
End-to-end Shopify storefront development for a wearable tech brand serving 2M+ users. I took the opal-earbuds product page from GTmetrix grade D to A (LCP 3.1s→1.4s, TBT 973ms→44ms) and rebuilt theme architecture plus custom automation.
Problem & baseline
Every case study starts with the real constraints, slow Core Web Vitals, manual workflows, conversion blockers, and a measured baseline (GTmetrix, PageSpeed, analytics) so improvements are provable, not anecdotal.
Solution & build
I document exactly what was changed: theme architecture, render-blocking scripts, image and CSS strategy, Liquid and request optimisation, and any custom automation that replaced manual back-office work.
Results with numbers
Each study ends with before/after metrics from the same test conditions, grade, LCP, TBT, CLS, plus the business impact, so you can judge the work on evidence.
Shopify & ecommerce case studies built on measurable results
As a freelance Shopify developer working with D2C fashion and lifestyle brands across the UK, US and Europe, I treat every engagement as a case study in the making. The flagship example is Zero Lifestyle, Pakistan’s top wearable-tech brand, where I own the entire Shopify storefront for a base of more than two million users. The work spans theme architecture, Liquid optimisation, custom automation, and Core Web Vitals performance tuning that took a key product page from a GTmetrix grade D to a grade A.
More case studies, covering Shopify, WordPress, React and Laravel builds for fashion, lifestyle and ecommerce brands, are being documented and added here. If you need a Shopify developer who can show real before/after numbers rather than vague claims, get in touch for a free project consultation.
