The author has reviewed dozens of product design portfolios and is now sharing their insights on what makes a good portfolio. They argue that traditional approaches, such as Dribbble-style portfolios or overly detailed case studies, often fail to effectively communicate the value of a designer's work. Instead, they recommend presenting a list of links to products designed by the individual, along with short descriptions and screenshots, which can provide a more concise and effective way to showcase one's skills. This approach is particularly useful for designers who are busy or lack experience working on well-known products. The author suggests that even a plain text email with links can be an effective portfolio, as it allows designers to focus on the results of their work rather than the design process itself.
