Apr 1, 2026April 2026 – Harja CI stability and test reporting improvements. Stabilized continuous integration and test reporting for finnishtransportagency/harja by pinning action-junit-report to a specific hash and locking the junit report action version, yielding deterministic builds and more reliable test outcomes. Also added version annotations in CI comments to improve traceability and maintainability. These changes strengthen release confidence, speed up feedback loops, and demonstrate strong CI/CD discipline with GitHub Actions and dependency pinning.

Mar 1, 2026March 2026 (2026-03) performance and security uplift for the Harja repository. Delivered key CI/CD improvements, governance, and security hardening while stabilizing runtimes and enhancing observability. Business value centers on reproducible builds, safer dependencies, faster and more reliable deployments, and improved visibility into system health. Key features delivered: - CI/CD version pinning for AWS and Docker actions to guarantee reproducible builds and reduce drift (pinned aws-actions and docker actions across the pipeline). - Enabled GitHub Actions ref-pin and broadened CI coverage with Dependabot scans to improve security and dependency freshness. - Added zizmor.yml configuration to standardize deployment/scan definitions and streamline configurations. - Implemented fine-grained workflow permissions for Test Extra Browsers and Deploy workflows to tighten security and reduce blast radius. - Established dependency pinning governance (hash vs ref pinning) and cooldown policies to balance update velocity with risk, improving PR hygiene. - Observability and analytics improvements, including time-based analytics refinement and enhanced integration status visualization for better bottleneck detection. - Finnish terminology alignment: refactor of security references to tietoturva for consistency and clarity. Major bugs fixed: - Harja network cleanup when devdb is down: safely terminates network to prevent lingering connections during shutdown. - Security hardening: prevent credential storage on disk to minimize exposure and improve data protection. - Security hardening: mitigate template injection risk by restricting script scanning to the .github directory and applying read-only docker mounts in non-fix modes. - Quality fixes: correct typo in option checks and ensure proper usage of getMessage to prevent misinterpretations in error handling. - Dev workflow resilience: improved error handling in devdb_down.sh to reduce failed runs and improve recoverability. Overall impact and accomplishments: - Significantly reduced deployment risk through version pinning and stronger security controls. - Improved reliability and stability of CI/CD pipelines, with better dependency hygiene and faster, safer releases. - Enhanced visibility into system health and performance, enabling proactive optimization and quicker incident response. Technologies/skills demonstrated: - GitHub Actions, YAML-driven CI/CD governance, and hash-based pinning strategies. - Security hardening and threat modeling: credential handling, template injection mitigation, and restricted scanning scope. - Observability and analytics: time-based metrics, granularity enhancements, and status visualization. - Localization and terminology alignment (security to tietoturva) for user clarity and compliance.

Aug 1, 2025Month: 2025-08 – Harja (finnishtransportagency/harja) delivered targeted reliability improvements, stronger test stability, and CI automation refinements to accelerate PR validation and reduce production risk. Key features and fixes implemented in August are summarized below with business value implications. Key features delivered: - Cypress Dependency and Node Engine Alignment: Moved Cypress to devDependencies and aligned the Node engine version; updated build/scripts accordingly to reflect development-only Cypress usage. This reduces production footprint and clarifies tooling boundaries for developers. - End-to-End Test Stability Improvements: Introduced timeouts for loading states and refactored test setup to ensure consistent test initialization; results in more reliable E2E runs and faster, more predictable test cycles. - Clj-kondo Hooks for taoensso/encore: Added hooks for defaliases, defn-cached, and defonce; adjusted defalias hook mapping; introduced taoensso_hooks.clj for implementation; improves static analysis and linting quality for the Clojure components. - Pin GitHub Actions download-artifact to v5.0.0: Updated workflow files to pin actions/download-artifact to v5.0.0, enhancing CI reliability and reproducibility. - Cypress Click Reliability Fix: Removed force: true from Cypress click actions to ensure elements are actionable before interaction, reducing flaky tests. - Skip tuck-remoting notifications tests for stability: Temporarily skipped integration tests for tuck-remoting notifications to stabilize the overall test runs. Major bugs fixed: - Flaky E2E test issues and Cypress interaction reliability addressed through timeouts and removing force-based clicks. Overall impact and accomplishments: - Improved test reliability and CI stability, enabling faster feedback cycles and more predictable PR validation. - Clearer development tooling boundaries and more consistent build scripts, reducing maintenance overhead. Technologies/skills demonstrated: - JavaScript/Node.js, Cypress, GitHub Actions, E2E test design, test stabilization techniques, and Clojure tooling (clj-kondo) for static analysis improvements.
