Worked on stabilizing the initialization sequence of the Feature API within the Automattic/wp-feature-api repository, focusing on backend development using PHP. Addressed a critical issue where endpoints were not being registered before their routes, which previously led to execution failures and runtime errors. By restructuring the initialization to occur after the REST controller but before route registration, ensured that feature-driven endpoints are reliably registered and executable during deployment. This change improved startup reliability and established a more robust baseline for future feature deployments. The work demonstrated attention to deployment stability and a methodical approach to backend system reliability and maintainability.
