Error: 404 error for Kirill Feschenko link under Dynamic Realtime category

### Describe the Error
The link for "Kirill Feschenko" under the category Dynamic Realtime is incorrect

### Expected behavior
It should redirect to Kirill Feschenko's GitHub, but instead got to https://github.com/xcaq/xcaq, which cannot be found (404 error)

### Additional context
I think the correct link should be https://github.com/feschenko/feschenko

Find the file that lists profiles in the 'Dynamic Realtime' category, likely a markdown file in the repository. Locate the entry for 'Kirill Feschenko' and update the GitHub URL from https://github.com/xcaq/xcaq to https://github.com/feschenko/feschenko. Verify the change by checking the link locally or in a preview.
