PROFILE

Callum Macdonald

Over a two-month period, this developer enhanced policy-driven automation and governance across the mojaloop/iac-modules and mojaloop/iac-ansible-collection-roles repositories. They implemented centralized policy enforcement by deploying Kyverno via Helm and integrating it with Argo CD, enabling automated policy deployment and reducing misconfiguration risks. Their work included standardizing Kyverno installation and configuration using Ansible and YAML, improving Argo CD resource tracking, and refining image rewrite policies to support multi-cluster reliability. Additionally, they stabilized Vault storage and addressed deployment consistency issues, resulting in more reliable infrastructure as code workflows and improved compliance across Kubernetes environments through policy as code practices.

January 2025 focused on establishing centralized policy governance through Kyverno and Argo CD, delivering policy-driven automation across Mojaloop IaC modules and Ansible collections. By deploying Kyverno as the policy engine via Helm and integrating it into the core Argo CD GitOps root application, we achieved centralized policy enforcement, automated policy deployment, and reduced risk of misconfigurations in production. Standardization across repositories accelerates secure deployments and tightens governance, with measurable improvements in consistency and compliance across environments.
