Oh wow, this is going to be hard to tell, i’ve still got to make the site, but here are some general stuff.
I use Webpack/Grunt/Gulp, SCSS/Less, Babel, ESLint to speed things up and make sure that everything goes tickity-boo.
Then there is Git, Bower (RIP), NPM, BrowserSync, PhoneGap, cordova etc – to make everything works right
This is where I fall short, but I can setup Digital Ocean and AWS. Otherwise, best call someone else in for this bit.
