Sorry for late reply. When you have a wide experience, it is important to put a good level of description along the images from your work samples. My portfolio is a bit old but is an example of the point: https://www.behance.net/hanifbbz
If you omit the description, it is easy to be judged as just the UI designer and your UX/development skills might be overlooked. It is good to clarify your actual role in the creation of the product.
