Medical app
Built a time-boxed proof of concept for a self-diagnosis assistant that turns symptoms + basic user data into safe next steps: OTC suggestions or a GP visit. The app would then suggest widely accessible medications or propose an appointment with the local GP.

Discovery
Initial challenge analysis: 15-Minute Brainstorm
Writing down initial thoughts (part of the brand sprint) to gain insight into the problem and explore solutions (using the golden circle rule).
Success metrics
Preparing the most important KPIs for the MVP version to measure if the solution aligns with user needs.
User personas and their behavior patterns
Based on the most common user personas identified during competitive analysis, I sketched a simple flow showing the typical ways users achieve their goals.
Competitive analysis
Analyzing the most popular competing apps by building user flows from screenshots, evaluating features, and identifying the most optimized workflow.
Exploring health decision-making patterns
I conducted a brief survey to interview potential users. I surveyed 49 people between the ages of 20 and 50, representing diverse industries and lifestyles. The primary objective was to validate various features and user needs.
Ideation
Planning the MVP scope
Based on the previous exploration, I prepared an MVP scope that includes additional features for future releases.
First sketch of user-flow
The main goal was to create a general overview using low-fidelity wireframes. These wireframes would show how the app should guide users through the three main scenarios for the proof of concept:
- The user wants to check symptoms and understand what might be happening
- The user wants to confirm whether a doctor visit is needed
- The user wants to check symptoms and learn possible self-care options
Build
UX prototyping
Using the Ant Design library, I created high-fidelity wireframes, and prepared an interactive prototype in Figma. This allowed me to conduct initial usability tests with potential users.
Design the general UI
Designed the key UI screens to communicate the product vision and critical moments of the flow.
