Aligning header menus & social icons with image

I replaced the ‘title’ section of the header with an image, but now the menu links and social icons run adjacent to the top of the image. Can anybody provide the code to align with the bottom of the image and instructions where to insert the new code?

Thanks, my site is https://safayet.me

Also, if anybody could help me eliminate the empty space above the header too, I’d be grateful.
