As a web designer, wireframing is a skill that you can showcase in your portfolio to demonstrate your ability to think strategically, creatively, and user-centrically, as well as solve problems and communicate solutions. When selecting projects for your portfolio, choose the wireframes that you are most proud of and reflect your style and expertise. Aim to have a variety of projects with different goals, users, and contexts. Additionally, tell a story about the process and reasoning behind each wireframe. Describe the goal, user persona, research, sketching, testing, iteration, challenges and solutions, impact and value of your wireframes. If possible, use a tool or platform to create interactive wireframes or link them to a prototype or final design to make your portfolio more engaging and impressive. Lastly, ask your clients, colleagues or users for feedback and testimonials to add credibility and authority to your portfolio.
