Design methodology

Design system

I start with defining space fundamentals of the design system. Spaces will be used to create first global component: Grid.


Next, I create reusable components in Atomic Design Methodology to keep all of the UI elements as consistent as possible.


I collaborate with back-end and front-end developers during the implementation process to maximize the user’s experience on both sides.


In the conceptualization stage, I create low-fidelity wireframes for the control version and A/B tests. Next, I prepare high-fidelity prototypes based on the design system. During the implementation process, I work with developers to ensure the high quality of the final product. Last steps, QA like performance and usability testing. Finally, I can set all of the heatmaps, AB tests, and continue to improve the product in Agile Methodology.
