a broad understanding of software development and IT operations, while specializing in automation, CI/CD, or cloud infrastructure. Continuous Improvement DevOps is about creating more efficient, reliable, and scalable systems through continuous iteration. Systems Thinking DevOps requires the ability to think holistically about software delivery pipelines and infrastructure. 61
and finding ways to make processes more efficient? Am I curious about how systems work end-to-end, from code to deployment to monitoring? Am I comfortable with a dynamic role that requires constant learning and adaptation? Do I have a passion for improving the way software is delivered and maintained? Can I communicate effectively with both technical and non-technical stakeholders? 62
