About Me

I'm a Platform Engineer, whose main interest lies in computer science applications particularly in cloud operations, security, and observability.

With extensive experience running production workloads on Kubernetes, I specialize in deploying, scaling, and managing containerized applications, emphasizing system reliability, security, and developer experience. I have worked extensively with public cloud platforms including Google Cloud Platform, Amazon Web Services, integrating observability tools to maintain robust monitoring and incident response.

Since 2020, I have contributed at OneFootball Gmbh by leading the migration of over 100 microservices supporting 5 million DAU from an in-house Kubernetes platform to Amazon EKS. I architected GitOps workflows, enhanced cluster security posture, established comprehensive observability stacks with Prometheus and Grafana, and maintained 99% uptime. I automated cloud provisioning through pull-request-driven Terraform workflows, improving developer productivity and reducing review overhead by 75%, implementing a shift-left strategy to embed security and compliance checks early in the development cycle.

I started my career at Shieldsquare, a small startup as DevOps and leading Cloud infrastructure decisions. I managed hybrid cloud environments, optimized large-scale data pipelines, built data warehouses, and solved scaling challenges for billions of monthly requests through data engineering principles. Later in 2018, Shieldsquare was acquired by Radware, where I worked on advanced scaling challenges to protect web applications against automated threats.

Besides this, I follow football very closely and support Arsenal FC. I like , exploring distant places and always ready for a backpacking trip. :)

Currently, I am open to new challenges and eager to bring my expertise in cloud infrastructure, security, observability, and developer experience to innovative teams worldwide.
