Mobile is not responsive.

the about us part at the end seems a bit unexpected to be seen there. I would delete it and put the content on the first section, you have enough space for few line of text.
I would leave the last section for the contat part (toqeer.surge.sh/contact.html) that can be in the same page, no need an extra page for it. It's not always good to have a One page with one link that lead to another page.

Not responsive...
