About the project
SuperStvari is a Croatian web shop selling natural cosmetics, food supplements and cleaning products. I built the shop on a premium WordPress/WooCommerce theme and have looked after the technical side ever since: maintenance, servers, delivery and the custom work the business needs.
Scope of work
- shop build on a premium WordPress/WooCommerce theme
- regular maintenance and updates
- server migrations
- ongoing monitoring and optimisation of the shop and its performance
- integrations with delivery services and parcel lockers
- custom development as needed
Speed before and after
Before the optimisation the main content took over 12 seconds to load. The page weighed about 5 MB and felt frozen because the main thread was blocked.
