Our Work on home page and whole Portfolio section was built using a SP Simple Portfolio (more) component  and we used module published inside the SP Page Builder "Home" layout page.

To get similar results you have to configurate a SP Simple Portfolio component first. Start from adding tags.

Then you can add some items, of course with your own content inside.
