Optimization of the online store

Optimization of the online store on the outdated CMS Nespi has been carried out. Before the work began, the site loaded in 1 to 20 seconds, and under high load, errors and unstable performance occurred.

During the work, the system's bottlenecks were analyzed, routing was redesigned, caching of static data was implemented, and SQL queries were optimized. As a result, the page loading speed was reduced to 100–500 ms.

Additionally:
— support for WebP images was added;
— JSON-LD microdata was implemented to improve SEO;
— Ukrainian language was set as default;
— the retrieval of the list of branches on the cart page was optimized.

After optimization, the site became significantly faster, more stable, and better prepared for search engines.
