OfferUp Redesign
Aaron Doss, Andre Duong, and Jeremiah Viernes, 2025 Showcase
OfferUp Redesign: We worked on redesigning the OfferUp website to ensure that it complied with modern-day information architecture standards. To accomplish this, we conducted a research study to gather user feedback, built sitemaps and wireframes and developed a prototype. The site’s navigation was redesigned, then a user-centered card sorting test was performed to validate our changes and identify more issues we could have missed. We created a high-level and a low-level sitemap to display the redesigned website’s hierarchy and created a wireframe of the redesign. Finally, we created a prototype of our redesigned OfferUp website.
Our tests enabled us to properly redesign the site to address issues and produce a final website prototype that showcases its benefits to support user information tasks.
Aaron Doss: “I am pursuing a B.S. in Information Science and Data Analytics at San Jose State University. I have hands-on experience in public service and political data work, including managing the mayor’s office CRM for the City of San Jose, creating geospatial maps for a local political campaign, and supporting data and compliance projects for Loudoun County. Outside of work and school, I enjoy pickup basketball and am a devoted Golden State Warriors fan.”
Andre Duong: “I’m a Senior Year student at San Jose State University studying Data Analytics and Information Science. I love working with data to find trends and meaning behind the numbers to help inform others. I also do projects in 3D modeling, and I am minoring in digital media art. I hope to be able to use my knowledge I gained from the program and apply it to the real world in real jobs and internships.”
Jeremiah Viernes: “I am a fourth-year student at San Jose State University majoring in Information Science and Data Analytics. I am passionate about analyzing data to gain insights as well as making designs that accommodate users’ needs, goals, and behaviors.”
