Currently, lifestyle activity booking in Thailand faces challenges from traditional systems that are often delayed and lack social connectivity. JOYNMISE was developed as an integrated platform that merges activity booking with community engagement under the concept of "Shared Experience." The platform targets individuals interested in local experiences, workshops, and sports, while simultaneously supporting service providers. Key features include a real-time booking system, Community Matching, and a comprehensive Vendor Dashboard. The project enables users to seamlessly access activities and build new friendships, while business owners can reduce administrative workloads and cultivate customer loyalty through data-driven insights. Ultimately, JOYNMISE enhances the lifestyle business ecosystem, fostering sustainable growth by perfectly blending technology with human interaction.
