Apr 1, 2025April 2025 - navapbc/template-infra: Security hardening, visibility improvements, and documentation enhancements across the infrastructure stack. Key features delivered include: HTTP to HTTPS redirect for the load balancer, WAF protection for application load balancers with baseline rule sets and adjustable enable/disable, emoji status indicators for environment summaries to speed status assessment, and a reorganized infra documentation with absolute links and onboarding pages. Business value: increased security posture, reduced risk of unencrypted traffic, improved operator efficiency through quick status scanning, and faster onboarding. Technical accomplishments: applied AWS security features (ALB, WAF), implemented listener rules, managed WAF logging policy, and documentation modernization. No major bugs fixed this month.

Mar 1, 2025March 2025 performance summary for navapbc/template-infra focused on E2E testing framework improvements and reliability. Implemented on-demand E2E runs, end-of-deployment validation, and fixture-based test organization to accelerate feedback and increase deployment confidence. Centralized test utilities by moving libraries into lib and refactoring EmailService under e2e/lib, with on-demand config consolidated into e2e-tests.yml. Added e2e format checks and stability improvements such as ignoring HTTPS errors by default. E2E tests now run at end of deployment for final state validation. Misc CI/CD hardening and documentation updates completed to improve governance and developer experience.

Dec 1, 2024December 2024 monthly summary for navapbc/template-infra focusing on feature delivery to improve incident communication and automation. Delivered an automated system notification workflow 'send-system-notification' to standardize critical-event alerts across channels. The workflow dynamically determines channel types (e.g., Slack) and retrieves associated secrets using Terraform, and can be triggered manually or by other workflows to ensure timely notifications. This work reduces manual steps, speeds up incident response, and provides measurable improvements in cross-team visibility.
