I am a UX designer. My last project was working on a Coffeehouse shop application design. My role was as a UX designer. I used my knowledge of User Experience like Visual Designs which includes colors, typography, images, icons, gestalt principles. I began my designing process by empathizing with users. I had interviews with potential users. I built up User stories, User Journey Maps, personas, and problem statements. I also conducted a competitive audit. After going through the Empathy, Defining, and Ideation process. The next step was creating paper wireframes, digital wireframes, and low fidelity prototypes, then I conducted user research, I did usability study plans. I iterated on my lo-fi prototypes. Then I went for mockups and built up hi-fi prototypes, went for critique sessions, iterated on my designs, and TADA, when I saw everything in its proper position, users can use my design without any external guidelines, my project on coffeehouse was finished successfully. It took one and a half months. Of course, for the best user experience, you have to work a lot.
P.S. My current project is working on a flower shop's website that is going to be responsive.
