Would anyone know how to embed or connect my website jonathanmccallum.com so that my Hive @peakd posts show up there?

There are two options available:

• Use the EXXP plugin on Wordpress. When you write a blog post there, EXXP gives you the option of automatically cross-posting to Hive as well. Info here in their post: https://peakd.com/exxp/@exxp/introducing-exxp-the-rebranded-and-much-improved-replacement-to-the-steempress-plugin

• IF Wordpress supports RSS (I'm not sure if they do, or not), you can use an RSS tool to go the other way, so that when you post to Hive, your writing is cross-posted to your website. We have two on Hive:
  🔸 SuperHive https://peakd.com/dev/@bambukah/superhive-update-new-logo-new-code-new-features-and-better-future
  🔸 HiveRSS: http://www.hiverss.com
