During April 2026, contributed to the theopensystemslab/planx-new repository by designing and delivering the User Pinned Flows feature, which enables users to save and organize specific flows for quick access. This work involved backend development using JavaScript and SQL, including the creation of a new per-user data table and the implementation of role-based access control to ensure secure, scalable data management. Comprehensive automated tests were written in YAML to verify both access control and feature functionality. The focus on robust database design and test coverage laid a strong foundation for future analytics and enhanced user productivity without addressing major bugs.
