What I'm looking for

I'm looking to build and automate secure cloud platforms, improve Kubernetes reliability, strengthen observability, and solve production infrastructure challenges with cross-functional teams.

At DigitalOcean, I support production Kubernetes and GPU-based workloads, troubleshooting clusters, networking, storage, autoscaling, and deployments across customer environments.

I build infrastructure automation with Terraform, Argo CD, GitOps, and CI/CD pipelines. I also created internal AI support agents backed by a hybrid-RAG microservice, reducing MTTR by 17%.

Previously at Johnson & Johnson, I managed AWS multi-account environments, EKS clusters, cloud migrations, and observability platforms while reducing infrastructure expenses by 35%. My foundation in Linux administration includes automation, databases, enterprise networking, security hardening, and disaster recovery.
