Samiha Tahsin and Taslima Yasmin Tarin developed the Spice Jar restaurant management mobile application to address issues with the manual paper-based system used by restaurants. The app was designed using Adobe Xd and implemented using Android Studio with a Firebase backend. It allows customers to view digital menus, place orders, pay online or at the counter, and provides end-to-end order tracking to reduce wait times and paperwork for both customers and restaurants.
