Have you had tasks related to website performance optimization? How did you diagnose and solve slow loading issues?

To optimize website performance, I first conducted diagnostics using browser tools (Chrome DevTools) and services like Lighthouse to identify bottlenecks: slow resource loading, blocking JavaScript rendering, large images, etc.

Main steps for resolution:

• Minification and compression of CSS/JS.
• Lazy loading of images.
• Image optimization and compression.
• Using caching and CDN.
• Asynchronous script loading (defer, async).
• Reducing HTTP requests, combining files.

Example of using lazy loading for images:

<img src="image.jpg" loading="lazy" alt="Example">

I also analyzed server response times and, if necessary, optimized the backend or API to speed up data delivery.
