about me

I am an DevOps Engineer focused on automation, container platforms, and scalable delivery workflows. Previously worked as an DataBase Administrator.

I am Building Automated, Scalable Systems That Work Reliably at Any Scale

A background rooted in operating and optimizing high-demand data platforms—from transactional SQL systems to distributed NoSQL technologies—naturally led me to solving problems through automation. These early experiences revealed how systems behave at scale and sparked a long-term focus on reliability, performance, and operational efficiency.

Over time, my focus gravitated toward automation—the connective tissue that makes complex systems predictable, efficient, and resilient. This led me deeper into DevOps, where I could combine my data background with infrastructure-as-code, CI/CD practices, and cloud-native engineering. Today, Kubernetes and platform automation form the core of my work. I’m dedicated to designing environments that are not only scalable and secure, but also fully automated from deployment pipelines to operational workflows.

Throughout my career—whether working with SQL, NoSQL, or Kubernetes—the driving force has always been the same: build systems that run smoothly at scale, reduce manual effort, and empower teams through thoughtful, reliable automation.
