About

As a Senior Linux/DevOps Infrastructure Engineer with over 20 years of experience in the IT industry, I have honed my skills as a Linux system administrator and DevOps engineer. My extensive background encompasses DevOps, Linux, virtualization systems, and various Microsoft and load balancer products. At Mercedes, I design and implement high-quality automation, deployment, monitoring, and alerting tools for global operations. My responsibilities include creating and configuring both cloud-based and on-prem environments, performing maintenance and troubleshooting, and collaborating with business partners, developers, architects, and product owners globally. I am proficient in tools and technologies such as Docker, Kubernetes, Jenkins, GitHub Enterprise, GitLab, and various cloud environments like Google Cloud, Azure, and AWS. Additionally, I possess strong scripting skills in Bash, Groovy, PowerShell, and Python, and I am experienced in managing CI/CD pipelines, high availability, secure environments, and compliance requirements. Prior to my current role, I worked at Istanbul's EPIAS as a Senior Linux System Engineer, where I managed large-scale installations and container architecture. My experience also includes positions at TurkTelecom, DEFACTO, Ora GYG A.Ş., Turkcell, and Aydın University, where I managed Unix and Linux servers, virtualization systems, and a variety of IT infrastructure projects. I hold an Associate Degree in Computer Programming, a Master's in Management Information Systems, and a Bachelor's in Business Administration, all from Istanbul University. My professional skills include excellent communication, project leadership, and strong problem-solving abilities, with advanced expertise in Linux/Unix systems, DevOps tools, and virtualization.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
