Performance
- Slow pages that failed Google's speed standards
- Heavy scripts and images delaying load times
- Pages doing far more work than needed to load
- Years of legacy code slowing everything down
Infrastructure
- Frequent outages, often at the worst moments
- Caching too weak to handle real traffic
- Servers crashing under load spikes
- Product data flowing in too slowly
Stock Management
- Stock counts that didn't add up
- Inventory wrong across different markets
- Orders shipping from warehouses that were out of stock
Our solutions
Five pillars, one integrated transformation.
Asset Bundling Redesign
Disabled default Magento JS bundling; custom strategy via modern build tools.
Intelligent Image Loading
Lazy-load for hidden menu images, cutting unnecessary downloads.
CSS Optimization
Restructured CSS to minimize render-blocking and layout shifts.
Script Efficiency
Prevented invisible sliders from initializing, reducing JS execution.
"Before we called KNYR, a customer in Berlin could order two products and one of them would ship from a warehouse that didn't actually have it. The site went down regularly, sometimes for hours, usually on the days we could least afford it. I'd stopped checking my phone on weekends because every notification was bad news. Now it's quiet. Best money we've spent."
— Matthias, Head of E-commerce
