Tomas Kamsäter focused on improving the stability and reliability of the cafe booking experience in the Dsek-LTH/web repository. He addressed a persistent UI issue by removing the malfunctioning CafeBookingCalendar component and introduced a temporary submit control to maintain immediate shift assignment functionality while a more robust useEffect solution was pending. Working primarily with Svelte and JavaScript, Tomas also corrected the logic governing time-slot availability to ensure accurate user eligibility for shift sign-ups. His work emphasized clear traceability and delivery continuity through targeted hotfixes, demonstrating a methodical approach to maintaining front end stability and booking logic integrity.
