Hey, I'm Osman.

DevOps Engineer & 3× AWS Certified
— I build, automate, and scale things in the cloud.

I'm passionate about Kubernetes, infrastructure as code, and making complex systems reliable and observable. I also write about what I learn — because good knowledge is meant to be shared.

About Me

A bit about who I am

I'm a DevOps Engineer focused on cloud-native infrastructure, with deep hands-on experience in AWS, Kubernetes, and the modern DevOps toolchain. I care a lot about building systems that are not just functional, but observable, resilient, and a joy to operate.

Beyond the day-to-day work, I enjoy writing technical articles — breaking down complex cloud and DevOps topics in a way that's actually useful for other engineers. I believe that clear documentation and knowledge sharing make our whole community stronger.

When I'm not automating things, I'm probably exploring a new café in Antalya or diving into a good series recommendation from a friend. ☕
