As we watch COVID-19 sweep the world, many feel a call to help. This brief gives us designers the opportunity to make a contribution with our creativity. The COVID-19 problem that I chose to focus on is the need for more home care and self-diagnosis in order to avoid overwhelming hospitals.


Many pressing COVID-19 problems exist, but many (like not having enough ICU beds or ventilators) do not lend themselves to digital solutions. After considering the level of need and digitization of brainstormed problems, I identified that home care and tracing were the ones with the most potential.


To enable home care as best as possible, I created an app that triages people with cold and flu symptoms based on their symptoms, risk, and exposure. After determining a person's overall risk, the app offers care knowledge, tele-monitoring, and follow ups to ensure the person is getting treatment.


I brainstormed problems associated with COVID-19, which I analyzed based on level of need and potential to solve digitally. Then, I interviewed people with cold and flu symptoms and people who are treating COVID-19 patients in hospitals. Home care surfaced as a concern on both sides - people who are sick prefer to stay and treat at home if possible, and hospitals are already overwhelmed. With home care, I focused on the self-diagnosis flow because tele-medicine services for clinicians to screen and monitor patients remotely already exist. I combined the top concerns expressed by people who were sick with CDC information and recommendations regarding COVID-19 to create a self-diagnosis flow to triage people with cold and flu symptoms. A key part of self-diagnosis that doesn't exist yet in other tools is tracing potential exposure, and tracing is another top issue that surfaced during research. Thus, I also included a feature to make it easy to trace potential exposure to COVID-19.

Design System

I aimed to make the app simple and soothing for a user that is sick and stressed. The progress indicator that is at the top of most screens breaks the self-diagnosis flow down step by step. I also chose a calm teal as the base color, with yellow to highlight important information. To make tracing easier, I included the ability automatically detect instances of potential exposure to COVID-19 when the user shares his location. However, if the user does not wish to share, she can also manually mark instances on a map that displays locations where people diagnosed with COVID-19 have been and when. For further development, this self-diagnosis flow requires clinical input on the steps involved, and the tracing feature will only work if tracing data for diagnosed COVID-19 patients is available. The remainder of the app (after the self-diagnosis flow) also needs to be further expanded to include scheduling, telemedicine functionality, and a monitoring/follow up flow.

It's not goodbye, it's see you later!

We have decided to sunset our Dream Projects Career Coaching service until we can properly devote our time and attention to this space. We feel passionate about helping young designers achieve their dreams and know that building a great portfolio is the first step. However, it requires a lot of time and attention to each individual and for that we strongly recommend a good career coach.

If you are interested in 1:1 career coaching there are many specialist that can help you one on one. However, if you would like a thoughtful review of your candidacy and some feedback about your resume, portfolio and presentation skills please apply to roles at
