Mücahit Ündemir - Senior DevOps Architect/Engineer | Kubestronaut

About Me

I'm a Senior DevOps Architect/Engineer based in Vienna, Austria, with a strong passion for Azure Cloud and Cloud Native technologies. Currently working at SoftwareOne, where I architect and implement Azure cloud infrastructure and cloud native solutions for enterprise customers.

My journey in IT started in 2012, beginning with hardware management and Linux system administration. Over the years, I've worked my way up from managing physical servers and infrastructure to becoming a DevOps Engineer specializing in cloud native technologies, container orchestration, and modern infrastructure practices.

I specialize in designing and implementing scalable Azure cloud infrastructure, Kubernetes platforms, CI/CD pipelines, and managing enterprise-grade cloud environments. My experience spans from on-premise data centers to Azure cloud platforms, with a primary focus on Azure infrastructure.

When I'm not orchestrating containers, I enjoy contributing to the DevOps community, exploring new cloud-native technologies, and continuously expanding my knowledge through certifications and hands-on projects.
