• Project: Mahara
• As a Full-stack developer, I worked on a Catalyst-supported open-source web application - Mahara. Mahara is an e-Portfolio platform that allows students and professionals to keep track of their learning and record their competencies. The requirement was to create a web application that’ll allow Quality Assurance Analysts to spin up cloud instances of Mahara on the go – to test any updates/patches provided by the open-source community.
• The application was developed natively using the Java Spring framework (REST endpoints) and JavaScript React. To containerize the application, used a combination of virtualization tools (Docker) and container orchestration tools (Kubernetes). Also used Infrastructure as Code (IaS) software tools (Terraform) to define, set up, and manage Kubernetes clusters in an OpenStack cloud environment.
• The development of this application reduced the complexity of setting up the Mahara application locally by automating the process. This allows open-source community contributors and Quality Assurance Analysts to spin up multiple versions of the application within minutes.
