Freelance design brings together different briefs, formats and expectations. A list of disciplines can suggest variety, but it does not explain how I work. I find it more useful to describe the deliverable, the constraints and the decisions that connected the two.
A client can remain unnamed while the design problem stays specific. Explaining what needed to be communicated, what I contributed and how the result was prepared gives the work a clear context. Confidentiality does not have to make the process vague.
