Hello! I'M
Shiera Bester.

UX/UI & PRODUCT DESIGNER

Having worked in several environments after attaining my advanced graphic
design diploma, I have tackled a range of challenges, responsibilities, and
personalities. I have learned that I am adaptable, positive, organized and best suited to working in an environment with which I am dealing with people. I am able to work efficiently on my own, or dynamically as part of a team.


My skills include being a well-organized user experience designer. Experience
in creating Apps and websites that are user-centric. This includes wireframing,
Information hierarchy, high fadelity UI, brand management, online user testing,
developing user stories, prototyping, analysis, user research(qualitative and
quantitative).
