Jon Buckley engineered robust cloud infrastructure and automation solutions across the mozilla/terraform-modules and mozilla/fxa repositories, focusing on CI/CD reliability, secure networking, and lifecycle management. He unified Docker image publishing workflows using GitHub Actions and Docker, modernized Terraform modules for Google Cloud, and introduced features like Private Services Connect for Cloud SQL and automated TLS certificate rotation for Fastly WAF. Leveraging technologies such as Terraform, Shell scripting, and JavaScript, Jon addressed deployment risks, improved cross-platform consistency, and reduced manual toil. His work demonstrated depth in infrastructure as code, cloud integration, and release automation, resulting in more predictable and secure deployments.

Month: 2025-09 — mozilla/terraform-modules Overview: Focused on TLS lifecycle automation in the Terraform modules for the Fastly WAF integration. Delivered a new TLS subscription force update option and implemented the related fix to allow forced re-provisioning of TLS certificates even when domains are already active. These changes reduce manual toil, improve deployment reliability, and strengthen TLS certificate lifecycle management. Key achievements: - TLS subscription force update option delivered in the Fastly WAF module: added variable subscription_domains_force_update to force TLS certificate re-provisioning by updating the TLS subscription when domains are active. Commit: b0e83cdbe7210b11f0fabef273be7a1158945dd3. Major bugs fixed: - Fixed ability to force domain updates on TLS subscriptions in the Google Fastly WAF integration, enabling updates to apply without removing active domains (aligned with the feature above; commit includes the fix). Overall impact and accomplishments: - Automated, reliable TLS rotations with zero or minimal downtime when domains remain active. - Reduced manual intervention for certificate re-provisioning; improved security posture and deployment predictability. Technologies/skills demonstrated: - Terraform module development and version control - Google Fastly WAF integration and TLS lifecycle management - Feature flag design (subscription_domains_force_update) and change management - Strong delivery focus aligned with business value: faster rotations, lower risk, and reproducible deployments.
