notice
DataCamp says Portfolio pages are being retired. The URL remains linked as historical learning evidence.

The provider has deprecated portfolio pages. The historical public link remains attached without inventing unavailable projects or credentials.

03 / Boundary

Collections, not borrowed credentials.

Public links establish the artifacts they show; they do not turn old profile labels into current employment or upgrade recorded study into a completed degree.
