Need an expert in Jenkins

Job ID: 32996185

Budget: $10 – $30 USD

I have a website on my local server, which already has Jenkins configured (by another web developer) but I don't know how this system works.

1. I need someone who is an expert in Jenkins to explain to me how this system works and how to run it on my local server (Mac)
2. The website has 3 files: Jenkinsfile, Makefile, Dockerfile, I need you to explain to me how these files work.
3. The Makefile file already has a "watch" system to see the changes and compile SCSS, I need you to explain to me how to activate this.
