Profile

Cloud & DevOps Engineer with 3+ years of experience designing and operating cloud-native and hybrid infrastructures (AWS + on-prem).

I specialize in building reliable, secure, and scalable platforms using Kubernetes, Terraform, and CI/CD pipelines, with strong focus on observability, DevSecOps, and cost optimization.

I enjoy working on production systems, automating workflows, and improving how teams deploy and operate applications efficiently.
