Overview
Negative Online is a Bulgarian fashion retailer whose WooCommerce store had grown sluggish as their product catalog expanded. Heavy page builders and unoptimized modules were dragging down performance.
We rebuilt critical modules from scratch to be lightweight and efficient, optimized the entire product catalog workflow, and implemented targeted caching - cutting load times by more than 50%.
Overview
Negative Online is a fashion e-commerce brand with a loyal customer base and a growing product catalog. As their store expanded beyond 2,000 products with seasonal collections, the site’s performance degraded noticeably. Category pages took 5+ seconds to load, the mobile experience was frustrating, and conversion rates were declining.
The root cause wasn’t the hosting or the traffic volume - it was architectural. The site relied heavily on a page builder that loaded its entire framework on every page, regardless of whether it was used. Product variation selectors were generating dozens of unnecessary database queries. The cart and checkout flow loaded scripts for features that weren’t even active.
Rather than applying patches, we rebuilt the critical customer-facing modules from scratch. The new product grid component loads in a fraction of the time because it queries only what’s needed and renders with minimal JavaScript. The variation selector was rewritten to use a single optimized query instead of the default WooCommerce approach of loading all variations upfront. We replaced the page builder on key landing pages with lightweight, purpose-built templates.
The image pipeline got special attention: we implemented WebP conversion, responsive srcsets, and lazy loading that respects the viewport - above-the-fold images load immediately while everything else waits. Combined with Redis object caching and a tuned CDN configuration, the store now loads in under 2 seconds even on mid-range mobile devices.
