Our Featured Case Study

We have created a digital guest service solution for our partner in the hospitality industry. ServeMe is an innovative solution that transforms how businesses engage with their customers. The process entailed developing a cross-platform mobile app from ideation to minimum viable product (MVP), with a focus on identifying the challenges encountered by users in the hospitality sector.

Improve user location

We integrated iBeacon and NFC technologies into our app, allowing for more accurate indoor positioning. By utilizing geofencing techniques, we were able to alert staff when guests are near certain areas. We also enhanced the platform components by integrating Socket.IO for real-time notifications. As a result, the staff can receive guest requests instantly, promoting efficient communication and enhancing customer satisfaction.

Streamlining the user entry process

To improve user retention further, we focused on streamlining the user entry point. After conducting UX testing, we determined that our previous process was too complex for users. As a result, we developed a new React-based web app that eliminated the need for downloads or configurations. This resulted in a 200% increase in user entry rates and a 50% increase in mobile app downloads.

Delivering robust data security across all system components

Through multiple stages of review, including code review by two developers, static code analysis tools, QA team review, business review, and UX development teams, we ensure compliance with the highest security standards. We achieve over 90% unit test code coverage for all parts of the product and perform security and penetration testing to minimize vulnerabilities and unauthorized access, ensuring reliable and secure interactions with the app.
