Senior Product Designer


My name is Dima Demian, originally from Ukraine. I'm a product designer with experience more than 16 years. Throughout my career I have had the pleasure of partnering with various companies to help them build products and services.

I’ve been designing stunning and user-friendly interfaces of websites and mobile apps. Additionally, I've worked on branding, UX-UI, interaction design, motion design, ad campaigns’ materials, 3D, interactive multimedia, and other commercial and creative projects. My passion is to deliver beautiful design solutions that effectively work.

My latest experience

Harmonize Health

That was design of sophisticated and intuitive platform that has been used by a number of leading healthcare providers, including Intermountain Healthcare, Choice Medical Group, MedStar, P3 Health Partners, and Stanford Health Care.

Whole Platform UI has been designed from scratch. This central repository of patient profiles that contain all necessary information about a patient's health, including the latest trends and conditions. Providers quickly and easily access all they need.

Information architecture of the platform sections underwent rigorous design and user testing, resulting in an enhanced ability to interact with any level data. This, in turn, has led to a significant increase in the number of patients that can be processed within a given time-frame.

Medication section is one of the platform’s vital components. With the mobile app, patients are empowered with full control over their medication and are alerted by notifications to ensure they never miss a dose. And healthcare providers in turn are able to stay up-to-date on patients' medication adherence, allowing them to provide tailored care and treatment.

The mobile app has been thoughtfully designed to run smoothly on both Android and iOS platforms. To ensure a seamless user experience, extensive testing conducted and incorporated insights from age and physiological characteristics of patients. This attention to detail has resulted in the app that is intuitive, easy to use, and tailored to the specific needs of patients.


During two years since 2017 as a head of design, I had a great opportunity to build a complex product from scratch. It was an advanced aggregator of different carriers and Online Travel Agency, with thousands of users daily.

The service UX/UI design was developed taking into account all user flow steps, such as searching and building simple and complex combined itineraries with advanced filter functions, booking process, payment, notification, getting and confirming all the necessary tickets. 

Working alongside with the marketing department, a distinct travel blog was developed and promoted. At the same time, a high level of activity in social media was maintained to retain old users and attract new customers.

Using tools like Google Analytics, Usertesting.com and Hotjar made it possible to create and configured deep analytics to fully track the number of users, their interaction with the service, conversion rates, reasons for successful or unsuccessful flows, and more. That allowed to make quick changes into the product in response to user pains and requests.

At the very beginning of the project, there were only dozens of users per month. Then, over the course of two years of operation and constant improvements to the design, front-end and back-end, the service was visited by thousands of users daily.
