Overview

High-end fashion brand with modern aesthetic and lightning-fast performance

Rhythm of Life is a high-end fashion brand with a modern aesthetic. I was responsible for leading the technical architecture, custom development, and performance optimization of the e-commerce platform. The goal was to deliver a pixel-perfect, lightning-fast online store with high visual fidelity and seamless user experience — all while maintaining clean, maintainable code.

We used Shopify as the base for scalability and stability, but extended it beyond default limitations with deep Liquid templating, custom JavaScript logic, and performance-first front-end practices.

🧠 Tech Stack & Engineering Overview

Frontend:

  • Custom Shopify theme built with Liquid, SCSS (BEM methodology), and vanilla JS
  • Product filtering with AJAX collections (dynamic rendering, no reloads)
  • Custom cart drawer with real-time inventory sync
  • IntersectionObserver & native lazy loading for image efficiency
  • Responsive breakpoints with fluid typography and grid layout
  • SVG sprite icons, inline asset delivery for better paint times

Performance Optimization:

  • Lighthouse tuning: LCP < 2.5s, CLS < 0.1, TTI < 2s
  • Asset bundling and critical CSS extraction
  • WebP image delivery + CDN-based caching for all assets
  • JS hydration strategy for interaction-heavy components

SEO & Metadata:

  • JSON-LD structured data for products, breadcrumbs, and pages
  • Meta automation via Shopify metafields + fallback logic
  • Canonical URL setup + clean pagination & robots.txt configs

Backoffice / Admin:

  • Metafield-driven CMS for non-dev updates (products, lookbooks, banners)
  • Sections everywhere: fully modular JSON templates with dynamic schema
  • Custom liquid logic for conditional layouts, campaign timers, and geo-based banners

Checkout Optimization:

  • Custom upsell logic pre-checkout (Shopify Plus script injection)
  • Multi-currency support using Shopify Markets
  • Analytics hooks via GTM + Shopify events

CI/CD & Workflow:

  • Theme version control using Git + Shopify CLI / Theme Kit
  • Development in Theme Dev environments
  • Codebase linted with Stylelint, Prettier, manual QA + staging pipeline

🚀 Outcomes & Metrics

Key Results:

  • 38% increase in mobile conversions within 90 days
  • Load times under 1.5s globally (thanks to lazy loading + CDN)
  • Bounce rate reduced 26% via interaction-first UX design
  • Cross-platform compatibility tested on 12+ breakpoints and browsers
  • Built scalable for future expansion into headless (Hydrogen-ready)
