A part-time user experience (UX) professional works to design, develop, and improve the elements that affect the experience for the user of a website, software, or application. Your job duties often include performing research to find out the expectations of users. You create graphic elements, test the user interface (UI), and ensure that interaction between the user and the software or site is intuitive and easy to understand. You can use many different programming languages for this, but your employer may have a preference. As a part-time worker, you handle your job responsibilities in less than 40 hours per week.
