PROFILE

Jérémie Mercier

Worked on the glpi-project/glpi repository, focusing on calendar export enhancements and event planning constraints. Delivered support for RRULE and EXDATE in iCalendar (ICS) exports, enabling accurate handling of recurring events and reducing manual corrections for users. Used PHP and JavaScript to parse and format recurrence and exception dates, improving interoperability with calendar clients. Later, implemented a strict 50-hour maximum duration for events, updating both backend logic and the user interface with Twig and JavaScript to enforce this constraint. These contributions improved data integrity, reduced scheduling errors, and enhanced the reliability and maintainability of event management features.

February 2026: Implemented a strict 50-hour maximum duration for events in the glpi project, hardened event parameter handling, and refreshed the UI to reflect the constraint. Fixed planning editability issues when durations exceed 50h, improving reliability and user experience. These changes reduce scheduling errors, enhance data integrity, and lay groundwork for future scheduling analytics; demonstrated robust JavaScript handling and maintainable code.
