During November 2025, contributed to the JabRef/jabref repository by delivering a feature that enables users to customize keyboard shortcuts within the Preferences interface. This work addressed a long-standing issue where shortcut bindings could not be edited or saved, improving accessibility and daily workflow efficiency. The solution involved implementing key event handling in the Java-based UI to capture new shortcut assignments and persisting these changes to the preferences repository. By focusing on UI development and thorough testing, ensured that user customizations are reliably stored and retrievable, demonstrating attention to usability, event-driven programming, and repository traceability within a collaborative development environment.
