As part of my role at work I am lucky to have access to some fantastic tools (and a few brains!) which have meant I have been able to setup my personal site with a few good tools from work.

Behind the scenes I have Drupal 8 in a canonical git repo on Github with my core codebase (less dependencies), a local fork of that repo checked out locally, Acquia BLT is one of those dependencies and setup in the codebase which helps to connect to Acquia Pipelines for CI/CD. Builds are then automatically made, tested and pushed to an environment on Acquia Cloud. From there I can further test, integrate and deploy the code up to a production environment.  Everything is proxied through Cloudflare which helps cache pages on their global CDN, provides a WAF, and lets me tweak things at the edge with Workers (if I want)
