Dec 2025 – Present · Killorglin, Ireland

• Built reusable GitLab CI/CD templates spanning Node.js, Gradle, Maven and Clojure, adopted by ten services across four language stacks, standardising build, test and release automation from a single source of truth.
• Shipped a GitLab CI Component for SAST, secret, dependency and container scanning, giving every project security coverage by default rather than per-team opt-in.
• Rolled out mutual TLS across seven payment microservices on AKS, provisioning an internal CA and per-service leaf certificates through Terraform, with key material delivered from Azure Key Vault via the Secrets Store CSI driver.
• Replaced long-lived registry credentials with Entra Workload Identity federation, giving CI keyless, short-lived authentication to Azure Container Registry, scoped per project and per branch or tag.
• Moved image promotion to build-once-promote-many with semantic-release, so a single immutable, digest-locked artefact is versioned once and promoted through environments rather than rebuilt at each stage.
• Built the Terraform and GitOps foundation for a multi-tenant AKS platform, covering landing-zone networking, per-tenant onboarding, Key Vault and workload identities, with all deployments delivered through ArgoCD ApplicationSets.
• Authored production Helm charts from scratch, pinning non-root UIDs, fsGroup and StatefulSet security contexts for PostgreSQL and Keycloak, and wiring JaCoCo, Cobertura and JUnit into merge request coverage diffs.
• Led observability rollout on AKS with Grafana Cloud, Prometheus, Loki, Tempo and Alloy, defining PromQL alerts for pod health and API server reliability.
