  • Bring the website metrics into the green zone of PageSpeed Insights.

    Web Programming
    A complete technical optimization of the website has been carried out to improve loading speed and achieve the highest scores in Google PageSpeed Insights.

    The optimization included:
    - setting up caching and compression (Gzip/Brotli),
    - removing blocking scripts and styles,
    - implementing critical CSS,
    - improving the loading of fonts and images (lazy-load, WebP),
    - relocating or excluding unnecessary scripts.

    Result:
    The website has been brought into the "green zone" both on desktop (100/100) and mobile devices (94/100), with zero delays (Total Blocking Time = 0ms) on PC and almost no layout shifts (CLS = 0.007 / 0.017).
  • Exceeding processor minutes on the server

    Databases & SQL
    Task:
    Reduce the load on the processor and MySQL server without losing WooCommerce website functionality.
    Result:
    MySQL load has been reduced by almost 4 times, as shown in the graph (see screenshot).
    The website runs faster, and the load is stably within acceptable limits.
  • Improve website loading to the green zone

    Web Programming
    Technical optimization of the site based on OpenCart 2.3.0.2.3 has been completed. The work included: Audit of site performance (PageSpeed Insights) Fixing critical errors CLS, LCP, TTFB Optimization of DOM, CSS, and JavaScript structure Configuration of caching, preloads, lazy loading Improvement of performance to the green zone on mobile and PC devices All changes were made without disrupting the functionality of the store. After implementation, Google PageSpeed metrics reached stable results in the green zone.
  • Find the cause and fix the server overload.

    Databases & SQL
    Diagnosed server load, over 12 million database queries per day, which led to 20 minutes of CPU time and over 8 million SELECT/UPDATE/other type queries.
    Optimized SQL queries, reduced the volume of record scanning and data transfer, which allowed for a decrease in load on the CPU and database. Changes were also made to the query logic on the application side.

    Result:
    The server has been stabilized, CPU load reduced by more than 10 times, the database is no longer overloaded, and the website's performance has become stable and fast.
  • Bring the website indicators into the green zone of PageSpeed Insights.

    Web Programming
    As part of this project, a comprehensive speed optimization of the website was carried out to bring its metrics into the green zone of Google PageSpeed Insights. The work included a detailed performance analysis, identification of bottlenecks, and their elimination.

    The website structure was optimized, unnecessary DOM elements were reduced, and JavaScript and CSS were minimized and deferred, which allowed for faster page rendering. A complete image optimization was also conducted: WebP was implemented, and lazy-load was configured, significantly reducing the page weight.

    In addition, caching mechanisms were improved both at the browser level and on the server, using gzip and brotli for resource compression. For additional acceleration, Cloudflare CDN was connected, which improved content loading speed and overall website performance.

    As a result, the website achieved high speed metrics, positively impacting SEO, user experience, and the effectiveness of advertising campaigns.

I am more than satisfied with the work done by Andrey. All requirements were met 100% on the project that other developers were unable to handle. I would like to note that Andrey conducts a deep analysis of problems and optimization at the code level, rather than trying to inflate ratings through hacks. I will definitely reach out again.
