OpenCart Optimization Expert

Project: online store on OpenCart.

Problems:

— the site periodically loads slowly

— sometimes a 503 error (Service Unavailable) occurs

— bot load has been observed previously

It is necessary not just to "speed up the site", but to find the cause and eliminate it.

What is required:

Conduct an audit:

— determine the causes of slow loading

— determine the cause of the 503 error (server / database / load / bots)

Optimization:

— reduce site loading time

— reduce server load

Configuration:

— caching (mandatory)

— connection and configuration of CDN via Cloudflare

— basic bot protection (rate limiting)

Frontend and data optimization:

— compress and convert images to WebP

— optimize CSS/JS

— optimize database queries

Expected result:

— the site works stably (without 503 errors)

— page loading within 2–3 seconds

— improvement in Google PageSpeed Insights scores

Requirements:

— experience with OpenCart

— experience in speeding up online stores

— understanding of the server side
