What is the best way to implement such a filter structurally?

Question

There is a list of blog news with an implemented (in-house) filter, the filter parameters are passed in the ardes line. Here, for example, filter by author: It is
site.ru/blog?author=32
necessary that when filtering by author, the address should be like this:

site.ru/blog/author-name?param1=value&param2=value...

At the same time, so that each such "page" of the author can be given unique meta tags for search engines. What is the best way to implement this structurally?
