During a three-month period, Daniel Lactin enhanced cloud infrastructure and CI/CD workflows across mozilla/terraform-modules and mozilla/experimenter. He delivered a Config Connector add-on for GKE clusters, enabling per-cluster lifecycle management through Terraform and improving governance by introducing an opt-in variable and resource configuration. In the same repository, he stabilized Google Workload Identity integration by refactoring service account handling and pinning dependencies to ensure predictable deployments. For mozilla/experimenter, Daniel restructured the GitHub Actions pipeline to publish Docker images to Google Artifact Registry, implementing explicit build, tagging, and push steps using Bash, YAML, and Docker, resulting in a more reliable release process.

In August 2025, delivered a streamlined CI/CD enhancement for mozilla/experimenter to publish Docker images to Google Artifact Registry. Replaced the previous reusable build/push action with explicit steps: build_prod via make, image tagging based on Git tags or commit SHAs, and pushing with a dedicated docker-push action. The workflow now has write permission granted to publish images. This work establishes a reliable, auditable publishing pipeline and sets the foundation for scalable image distribution.

May 2025: Delivered Config Connector add-on for GKE clusters in mozilla/terraform-modules. Introduced an opt-in enable_config_connector variable (default false) and added a config_connector_config block to the google_container_cluster resource to manage Config Connector per cluster. This enables per-cluster Config Connector lifecycle management, improves governance, and reduces manual setup during cluster provisioning. Full change captured in commit 1fc6d316d0be1ad54633e4231497766e91b5aa92.

April 2025: Delivered stability improvements and output-consistent changes for the Google Workload Identity module in the mozilla/terraform-modules repo. Implemented an initial refactor to use provided service account inputs, followed by a controlled revert to reintroduce the data source and align outputs with the prior state to minimize downstream impact. Strengthened production safety by pinning the google_workload_identity module to v2.6.1 in gke_service_account.tf, preventing unintended behavior from upstream updates and ensuring tested, predictable deployments.
