Katrina Tantay engineered robust security and user management features for Automattic’s vip-security-boost repository, focusing on backend development, CI/CD, and code quality. She delivered systems for tracking privileged activity, enforcing multi-factor authentication, and notifying administrators of critical events, using PHP, JavaScript, and React. Her work included refactoring modules for maintainability, integrating Prometheus metrics for observability, and automating workflows with GitHub Actions. In wp-calypso, Katrina implemented headless initialization for the Agents Manager, streamlining integration with Image Studio. Her approach emphasized automated testing, configuration-driven design, and performance tuning, resulting in reliable, maintainable code that improved security posture and developer productivity.

February 2026: Delivered the Agents Manager Headless Mode in Automattic/wp-calypso, enabling initialization without a UI and smoother integration with Image Studio. This work improves automation, testing, and orchestration across components, reducing manual setup and accelerating integration workflows.

August 2025 performance summary: Delivered robust security platform improvements across vip-security-boost and a Site Editor enhancement in wp-calypso. Focused on reliability, performance, and data integrity, with targeted improvements to capability checks, MFA data flow, and URL parameter propagation in AI Site Builder. These changes reduce risk of infinite loops, remove plugin dependency for MFA reporting, strengthen caching, and modernize the Highlight MFA Users module, while maintaining testing and linting discipline.

July 2025 for Automattic/vip-security-boost focused on reliability, security, and maintainability. Delivered a WPComVIP handling refactor, capabilities-driven enhancements across MFA and inactive-user workflows with feature toggles via config hash, and auditing improvements by logging user_login events when skipping notifs. Implemented performance and maintainability tweaks by skipping WPComVIP processing for inactive users and centralizing bot user retrieval in utils/class-configs.php. Included a substantial quality push: stabilizing tests across modules, addressing lint and PHPStan issues, and hardening error handling (VIP_CONFIG_API_URL) and related edge cases. The result is cleaner code, fewer flaky tests, improved observability, and stronger business value through predictable behavior and auditable actions.

April 2025 monthly summary for Automattic/vip-security-boost: - Delivered MFA visibility enhancements, including highlighting MFA-disabled users, renaming the mfa-users view to highlight-mfa-users, and adding notices with navigation for filtered views. Also fixed backslash handling in the MFA plugin to improve reliability when parsing MFA data. - Expanded MFA coverage and configurability: extended MFA checks to include users with the edit_posts capability, introduced a capabilities-driven config for highlight-mfa-users, and updated the MFA-disabled count to include edit_posts users. - Strengthened testing, documentation, and QA: updated README to reflect unit tests and linting, added a unit test, and updated the unit test workflow; reorganized tests into a phpunit structure and added an unit test for forced-mfa-users. - CI/CD, linting, and PHP standards improvements: updated workflows to run on PRs, integrated phpcs into composer, set PHP version to dev, updated PHP CS ruleset, and performed lint fixes across the repo; removed Node from PHP unit tests workflow where applicable; removed psalm-related config and references. - Stability, loader and refactor improvements: corrected class loader behavior for class- prefixed files, added class- prefix to forced-mfa-users, and performed module renames and utility improvements to simplify config retrieval; addressed bootstrap and filter issues to stabilize the release. - Business impact: enhanced security posture with 2FA enforcement readiness, reduced maintenance burden through unit tests and linting, and improved deployment reliability via CI/CD and code quality improvements.
