Experience

  • WebLogic Domain Creator (Development)

    A Golang-based application for creating and automating the WebLogic domain. I was the sole developer of this application. The tool allows for the creation of full, sophisticated WebLogic domains from YAML definition (database, JMS, etc). This tool allows a domain to be created from code that enables speed, simplicity, consistency, risk mitigation (i.e. human error), and is repeatable.

  • Cloud Migration (Development)

    I was in the cloud core team responsible for the migration of Linux Red Hat and Windows servers, on-prem Kubernetes clusters, Docker containers (Swarm and Docker EE) to the Azure cloud using Terraform and Packer.

    I designed and maintained dozens of CI/CD pipelines on Azure DevOps responsible for building the source codes, creating Docker containers and Helm charts for production deployment. Incorporated code scanning with SonarCloud and Docker image scanning with Harbor and Aquasec.
