WordPress + GitHub
If you’ve been building client websites for a while, you may remember a time before WordPress. A time when building websites meant creating every HTML page by hand. At some point, you probably decided that there were common features that every customer needed on their site, so you started using one customer’s website as the template for the next. Of course these days, WordPress is the underlying software for many modern websites, and there’s no need to re-invent core functionality.
