A portfolio makes a skill visible through examples. A finished image or file can be useful, but a short explanation of the problem, constraints, and decisions helps a reviewer understand your role. Choose a few relevant projects. For each, state the objective, your contribution, the tools used, and the result. Include a small sample or demonstration that you have permission to share. Explain one trade-off and one improvement you would make. A beginner can create a clearly labelled practice project. Do not present a fictional client as a real customer. Remove private data and respect ownership of work created for an employer or a team. A broken link can make strong work difficult to assess, so test access. Practice: Prepare one project page containing the problem, your approach, the output, and a short reflection. Ask a reader what remains unclear.
