Reija Laukko developed a configurable Student Feedback Reminder System for the UniversityOfHelsinkiCS/palaute repository, focusing on backend development and configuration management using Node.js and JavaScript. She replaced the deprecated SEND_AUTOMATIC_REMINDER_ALWAYS flag with a new SEND_STUDENT_AUTOMATIC_REMINDER_ENABLED setting, updating the reminder dispatch logic to respect this configuration. By enabling automatic reminders through a centralized setting, her work improved maintainability and aligned with the repository’s deprecation roadmap. The new approach allows reminders to be toggled without code changes, supporting better feedback deadline adherence and reducing late submissions. This feature demonstrates thoughtful engineering within a short project period and clear technical depth.
