What I'm looking for

I seek a hands-on DevOps/cloud role where I can design scalable AWS infrastructure, improve CI/CD pipelines, reduce operational toil, and contribute to a collaborative, growth-oriented engineering culture.

I am a Senior DevOps Engineer with 15+ years focused on cloud engineering, infrastructure as code, and CI/CD automation. I specialize in designing and operating scalable AWS environments and automating deployments to improve reliability and velocity.

Throughout my career I have implemented Terraform-based provisioning, built Jenkins and Spinnaker pipelines, and managed container platforms such as ECS and Kubernetes. I routinely tune Java Spring Boot applications and optimize PostgreSQL databases for production workloads.

I emphasize observability and operational excellence, implementing monitoring with Splunk, Dynatrace, Prometheus and Grafana, and integrating Airflow for data pipeline orchestration. I also automate routine maintenance with Python to reduce toil and improve uptime.

I collaborate cross-functionally in Agile teams, document architectures and runbooks, perform cloud cost analysis, and lead multi-region deployments to ensure redundancy and fault tolerance. I bring a pragmatic, problem-solving approach to complex infrastructure challenges.
