Callum Macdonald engineered centralized policy governance and automated policy deployment for Mojaloop’s infrastructure, focusing on the mojaloop/iac-modules and mojaloop/iac-ansible-collection-roles repositories. He integrated Kyverno as a policy engine using Helm and Argo CD, enabling policy-driven automation and consistent enforcement across Kubernetes environments. His work included developing Kyverno-based image rewrite policies, standardizing configuration management, and stabilizing Vault storage through precise PVC sizing. By leveraging Ansible, YAML, and GitOps workflows, Callum improved deployment reliability, reduced configuration drift, and enhanced compliance. The depth of his contributions is reflected in the robust, maintainable policy management and deployment processes he established.

February 2025 monthly summary focusing on delivering policy-driven governance, deployment reliability, and streamlined setup across the iac-ansible-collection-roles and iac-modules repos. Emphasis on ArgoCD resource tracking, Kyverno-based image rewrite governance, and stabilized storage/configuration to reduce diffs and outages in multi-cluster environments.

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.
