To transition from a Senior Data Analyst to a DevOps Expert, focus on acquiring skills in automation, scripting (e.g., Python, Bash), infrastructure as code (e.g., Terraform), containerization (e.g., Docker), continuous integration/continuous delivery (CI/CD) pipelines, and cloud platforms (e.g., AWS, Azure). Obtain relevant certifications to validate your expertise in DevOps practices and tools.
