Kentsanggds

Ken Tsang engineered robust deployment automation and infrastructure improvements across key GOV.UK repositories, including alphagov/release and alphagov/govuk-infrastructure. He developed multi-app Kubernetes deployment frameworks, unified deployment visibility in application UIs, and streamlined cross-environment IAM role assumption using Terraform and AWS IAM. Ken enhanced reliability by integrating Argo CD and Helm for ephemeral and canary environments, while refining error handling and configuration management in Ruby and YAML. His work addressed deployment drift, improved developer experience, and strengthened security through granular RBAC and automated testing pipelines. The solutions demonstrated depth in cloud engineering, CI/CD, and infrastructure as code, supporting scalable, maintainable platforms.

Work History

October 2025

8 Commits • 6 Features

Oct 1, 2025

October 2025 monthly work summary focused on strengthening release governance, security, and canary testing across GOV.UK repos. Key features delivered include a Canary deployment setup for govuk-synthetic-test-app-canary across integration, production, and staging with image tag v1, disabled automatic deployments, and promotion enabled, plus environment-specific deployment parameters and ingress hosts. We explored granular Kubernetes RBAC for the synthetic test app to enable targeted pod-resource access, then reverted to restrict to pods to maintain least-privilege security. Additional CI/CD improvements added a canary repository to the release pipeline and introduced a required 'Test' status check, strengthening release validation. Security posture was further enhanced by implementing standard security checks on the govuk-user-reviewer repository. Lastly, the govuk-developer-docs integration was expanded by adding the canary test app repo to repos.yml with Utilities classification and team associations, supporting canary testing governance and monitoring.

Sep 1, 2025

September 2025 monthly summary focusing on business value and technical achievements for the Synthetic Test initiative across the primary Gov.uk repositories. Delivered foundational automation, governance, and deployment capabilities to enable scalable testing, secure cross-account access, and automated delivery pipelines.

August 2025

10 Commits • 3 Features

Aug 1, 2025

August 2025 monthly summary: Delivered cross-repo reliability, deployment automation, and maintainability improvements across alphagov/release, alphagov/govuk-dgu-charts, alphagov/govuk-infrastructure, and alphagov/govuk-helm-charts. Key outcomes include robust UI messaging for GitHub query failures, CKAN site URL templating alignment for local development, integration of govuk-synthetic-test-app into the deployment pipeline via Terraform management, and Helm chart configuration enabling the test app. Additional infrastructure cleanup reduced misconfiguration risk, improved security posture, and simplified operations. The work reduces user-facing errors, accelerates deployments, and improves environment parity and test hygiene.

July 2025

Jul 1, 2025

July 2025 performance summary focusing on delivering multi-app Kubernetes deployments, improved deployment visibility, and infrastructure modernization. Completed Licensify multi-app deployment configuration using k8s_apps.yaml and enhanced K8sHelper to determine the correct repo and namespace across multiple apps, including dedicated seeds and component mappings. Added a unified deployment view (Where is my code?) on the application show page to consolidate Kubernetes and GitHub deployment data and highlight discrepancies for faster reconciliation. Migrated UI to Kubernetes API data for running pods, leveraging app.kubernetes.io/instance labels and expanding the data model (k8s_data) to support richer Kubernetes information and Argo linking. Sourced latest version tags directly from GitHub with robust error handling to ensure accurate version visibility. Completed CKAN PostgreSQL 14 upgrades in both integration and staging environments, including Terraform state imports/cleanup and removal of obsolete files to streamline future upgrades. These changes reduce deployment drift, improve developer visibility, and strengthen platform reliability and upgrade readiness.

Jun 1, 2025

June 2025 monthly summary: This month delivered tangible business value by improving deployment visibility, reliability, and cross-account deployment workflows across AWS and Kubernetes. Key outcomes include enhanced Kubernetes deployment visibility and robustness with per-environment image tagging, improved resilience in deployment data retrieval, and targeted bug fixes for AWS STS and Kubeclient HTTP errors. We also added a reusable Argo CD App Link Helper, refined seeds/configuration to align with Kubernetes conventions, and enabled cross-environment IAM role assumption for non-production environments to streamline multi-account deployments. These efforts reduce toil, accelerate troubleshooting, and support safer, more scalable deployments across all environments. Technologies demonstrated include Ruby/Rails, Kubernetes, Argo CD, AWS IAM/STS, Terraform, and CI/CD tooling, with expanded test coverage and updated onboarding/docs to support developers.

Concise monthly summary for 2024-11 focusing on business value and technical achievement in alphagov/govuk-dgu-charts. In 2024-11, I prototyped a CKAN data cleanup workflow as a Kubernetes Job to remove duplicate CKAN data, then iterated on it with a rollback when deemed unnecessary. The work prioritized risk-aware experimentation and data hygiene enablement, delivering operational learnings and a reusable pattern for temporary automation.
