Oracle is a mobile app designed to help healthcare assistants, like nurses, track patient activity using state-of-the-art sensors embedded in IoT-enabled mattresses. These mattresses connect to a phone or tablet via WiFi, allowing users to monitor metrics such as patient turns, bed exits, and time spent in bed.

I was the sole Product Designer on a team of developers, working directly under the leadership of the CEO.

Over the course of four months, I meticulously crafted the user experience for both hospital administrators and regular users. I delivered a comprehensive wire flow, a mini design system, and all the necessary screens to bring the app to life.

We began by conducting interviews with 5 nurses, using a questionnaire to gather insights on how they would respond to various scenarios. Each scenario highlighted specific challenges we aimed to address with the app. I distilled the feedback into actionable design decisions, resulting in new layouts, interactions, and wire-flows.

A wire flow combines a user flow with wireframes. This was a critical step, as it gave developers early clarity on the technical aspects of the app. By showing how each screen connected to the next, we optimized the development process. Although it was a detailed and time-consuming task, it proved highly beneficial.

With the brand guide finalized, I created a mini design system and then designed all the screens for both regular users and administrators. Each user group had light and dark modes, as well as mobile and tablet views. In total, this meant designing 8 different views across over 400 screens.

This was the largest, most complex, and technically challenging project of my career. Designing so many screens on my own often felt overwhelming, as I had to balance legal, technical, and user requirements while maintaining simplicity and beauty. However, this project pushed my skills to a new level, and I’m grateful for the growth it brought.
