- Task
- Sell sweets, snacks and gift sets with delivery across Ukraine: catalog with filters by type and purpose, basket with delivery options, online payment. A separate emphasis is on the speed of the mobile version, because in the niche most orders are impulse and from the phone.
- Solution
- Shop on OpenCart 3.x using nginx with HTTP/2. Five online payment methods — LiqPay, WayForPay, Privat24, Visa, Mastercard — and four delivery methods, including courier and pickup. The condition of free delivery to the Nova Poshta branch from UAH 2,500 is posted on the main page; communication via Telegram, Viber, WhatsApp and Instagram.
- Result
- Measured on 07/31/2026: TTFB 402.9ms, full HTML load 532.4ms at 303.4KB - fastest first response among OpenCart stores of the batch. Defects found: it was not possible to measure the volume of the catalog from the outside, because /sitemap.xml gives HTTP 200 with a body of zero bytes, the feed of the site map is 404, and the theme does not display the counter of goods in the category; no analytics were found - no GTM, no GA, no pixel.
