  • Enhancing User Experience: Integrating ‘Hotel Fingerprint’ in Hotel Listings and Detail Pages

    In this case study, I integrate the 'hotel fingerprint' feature into hotel list and detail pages, highlighting top-rated amenities for families and couples. The study involves detailed analysis, hypothesis testing, stakeholder interviews, and user research. Visual concepts created in Figma demonstrate the implementation. Key metrics such as usability, accessibility, and user satisfaction are identified to measure success. This research aims to enhance the user experience by making it easier for users to find hotels that match their specific needs quickly and efficiently.

  • Re-design a feature, failure to success

    After observing low usage of Kondorliga’s Marathon feature, we identified issues through user feedback and data analysis. Users were confused by the feature's name and its separation from the time tracker. We conducted an open card sorting test, revealing that new users struggled to understand the feature. We redesigned the user flow to integrate the Marathon with the time tracker, resulting in a more intuitive experience. Post-update analysis showed increased engagement with the Marathon feature, validating our approach.
