About Me

You may think that this is just another static website. However, this was a project so that I can learn more about CI/CD. This server that you are on right now is actually hosted on my own home server.

My code is being deployed via Gitlab which has a continuous integration tool, so every time the master branch gets updated, a new docker instance begins to make a connection to my server and deploys the new updates! Pretty cool, huh? :-)
