- Task
- Sell gift sets next to the usual assortment, with delivery across Ukraine and online payment. The niche is impulsive, most of the orders are from the phone, so the speed of the mobile version was a separate requirement.
- Solution
- Shop on OpenCart 3.x using nginx with HTTP/2. In the checkout, there are five online payment methods and four delivery methods — from the carrier's office to pickup. Gift sets are listed in a separate branch of the menu next to other categories, of which there are more than a dozen in the menu. The main one is the condition of free delivery to the Nova Poshta branch from UAH 2,500.
- Result
- Measured on 07/31/2026: first server response 402.9ms, full HTML load 532.4ms at 303.4kB. Payments are confirmed on the delivery and payment page, four carriers are in checkout. Defects found: /sitemap.xml gives HTTP 200 with a body of zero bytes, the Sitemap line in robots.txt is commented out, so the search does not receive the sitemap; on the main zero JSON-LD blocks and no analytics counter — conversions are not counted anywhere. This is the state that we recorded by measurement, not the result of our work.
