With a total of 15 years of work experience, I have been providing consultancy services in the DevOps field for the past 5 years to both domestic and international companies. Over the last 2 years, I have particularly focused on improving CI/CD processes and DevOps infrastructures for financial institutions. Additionally, I have conducted projects on managing thousands of projects on different Kubernetes clusters using the GitOps approach. I am delighted to share the experiences I have gained.
