Bring the website metrics into the green zone of PageSpeed Insights.
Web ProgrammingA 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).

Bring the website indicators into the green zone of PageSpeed Insights.
Web ProgrammingAs 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.
