I'm Now a Certified Jenkins Engineer

Got my Certified Jenkins Engineer credential. I was in the first batch of people to take this exam, which felt like a milestone for the Jenkins community as much as for me personally.

The exam covers pipeline design (scripted and declarative), plugin management, distributed builds with agents, security configuration, and backup strategies. It's hands-on knowledge, not theory. You need to know what happens when a Jenkins master runs out of disk space (everything stops), how to configure LDAP authentication, and how pipeline libraries work.

Jenkins gets a lot of grief these days. People complain about the UI, the plugin compatibility issues, the Groovy scripting. Fair enough. But in 2016, Jenkins was the CI server. It was the tool that made continuous integration practical for most teams. I ran it for years across multiple organizations, and for all its quirks, it worked. The muscle memory from debugging Jenkins pipelines at 3am still kicks in when I'm troubleshooting CI systems today.
