I'm deep-diving into DevOps to bolster my resume. I've spent the last few weeks wrestling with Jenkins and Sonar on a home lab, but I’m noticing a massive shift toward GitHub Actions in recent job postings. If you were hiring a Mid-Level dev today, which would impress you more? Is knowing Jenkins and its complex ins and outs like Groovy pipelines, node management, and plugins worth it to most companies? What about osmeone hwo is not so proficient with Jenkins but has a lot of experience with Github Actions (or maybe even Gitlab and Bitrise CI/CD)? Is Jenkins only for legacy maintenance or is it still a core requirement for Big Tech and startup infrastructure?
