From systems support to cloud-native

DevOps Engineer with 5+ years of progressive experience — from Linux system support and on-premises deployment to cloud-native infrastructure. I build CI/CD pipelines, manage AWS and Kubernetes workloads, and set up end-to-end observability, with a strong focus on automation, security, and production reliability.
