UI Style Guide Features

Design system and features for clinical web application

As a UI Designer, I managed UI style guide of the main product. We extended the style guide which led to a more consistent UI, better usability, and an increased amount of designed features. For example, one of the new features sped up the management of patient documents that are frequently processed by staff of any clinic or hospital.

My way of designing...

How we will work together

I pay attention to understand project/business vision and to know well its customers & users. Then, I put effort to satisfy both sides and support also developers. That's my magic.

Together we will strive to achieve project goals and at the same time satisfy users’ needs. We will define the vision and learn about our users. Based on that we will produce Functional, Delightful Coherent solutions.

I will make sure all sources are well-organized and easily accessible by anyone from the team. I will create and manage UX guidelines to make our solutions unified and highly usable. We will also record and improve design processes to speed up our work. On top of that, we will set user experience metrics, which will help us to continuously create better solutions.

We will build quick interactive prototypes for user reviews and iterate our designs a few rounds. With developers, we will then co-operatively implement them. Finally, we will keep improving – based on the feedback from the users, based on the metrics, based on usability testing.

Is this the way of designing you like and support?

If yes, then great! We will get along well.
