What I'm looking for

I am looking for a role that fosters innovation, collaboration, and continuous learning.

As a Site Reliability Engineer with over 8 years of experience, I specialize in designing, implementing, and managing scalable and secure cloud-native infrastructures on AWS. My expertise lies in building and operating Kubernetes platforms (EKS) with a strong focus on automation, observability, and reliability. I am committed to driving best practices and cross-team collaboration to accelerate product delivery and improve system stability.

In my current role at Plenti, I have successfully designed and built a multi-tenant Kubernetes platform from scratch, optimizing infrastructure costs and enhancing security boundaries. My efforts in establishing GitOps workflows and implementing automated deployments have significantly improved deployment reliability and reduced operational costs. I am also a certified Kubernetes Administrator and Istio Associate, dedicated to continuous learning and professional development.
