Optimize WordPress Speed

I'm looking for a skilled WordPress developer to optimize my site's speed. Currently, I'm experiencing significant delays in various areas:

- Loading the homepage
- Navigating between pages
- Loading images and media

I'm using Hostinger, but I'm not sure if I've implemented any caching plugins.

The ideal freelancer should have experience with:
- WordPress speed optimization
- Working with Hostinger
- Caching mechanisms and plugins
- Identifying and resolving performance bottlenecks
