Tell about a situation with application performance optimization (mentioned in the resume) — why did the page load so slowly initially and how did you fix it?

Initially, the page loaded slowly due to a large volume of data being loaded at once and inefficient resource management: for example, heavy images without compression, lack of lazy loading, and a large number of synchronous API requests.

To optimize, I did the following:

• Implemented lazy loading for images and components to load only visible content.
• Used image compression and optimization.
• Split a large request into several smaller ones and implemented client-side caching.
• Converted some synchronous requests to asynchronous to avoid blocking rendering.
• Minified and combined CSS and JS files.

As a result, the page load time decreased from 8-10 seconds to 2-3 seconds, significantly improving the user experience.
