I do have experience with building my custom themes from scratch, so that won’t be a problem.
On all of my websites I try to use as little plugins as I possible can (Advanced Custom Fields, Yoast SEO, WPCF7)
I try to build most of the functionalities directly inside the theme, what would be my advantage of using Jetpack?
Maybe the Photon option within Jetpack will be useful but on the other hand, the website i’m planning won’t be using a lot of images.
Again, thank you for your assistance.
