Current Role

I work as Staff Engineer at VMware. My role primarily involves technical leadership of the SRE team. I create cloud infrastructure automation as well as continuous integration (CI) and continuous deployment (CD) pipelines. I design and implement solutions that meet our current and future requirements using tools such as Python, Kubernetes, Istio, Envoy, ArgoCD, Helm, Docker, Ansible, Jenkins, Terraform, MongoDB, Go, and SaltStack, on cloud platforms like Microsoft Azure and Amazon AWS.

My development tools include Python, Go, Docker, Ansible, SaltStack, Jenkins, git, PyCharm, Visual Studio Code, bash, JSON, YAML, GitHub, GitLab, JIRA, and MacPorts. Operating systems in use daily are macOS for my development box, and Ubuntu for infrastructure.
