Your portfolio is your showcase of your systems design work. It can help you demonstrate your skills, experience, and achievements to potential employers, clients, and collaborators. You should build your portfolio with care and attention, selecting your best and most relevant projects. You should also update your portfolio frequently, adding new and improved work. Your portfolio should include clear descriptions of your role, process, methods, tools, and results for each project. You should also use visuals like diagrams, screenshots, mockups, and videos to illustrate your work. Building your portfolio will help you attract opportunities, impress stakeholders, and stand out from the crowd.
