February 2026: Delivered a modernization sprint for the rca-wagtail-2019 project focused on security, maintainability, and reliability. Upgraded core stack (Django 5.11, Wagtail 7.2) and dependencies to reduce security risk and enable new features, improved Cloudflare integration for header security and performance, and updated CI/CD with PostgreSQL alignment. Enhanced admin UX with autofocus on the first error field. Hardened security by updating urllib3 and Node tooling, and modernized tooling with Python 3.13, upgraded linters/formatters, and re-linting. Result: stronger security posture, smoother deployments, and a more maintainable codebase with faster iteration cycles.
