ePortfolios are increasingly being used to illustrate personal/professional development and achievements in teaching. I see significant value in creating my own personal teaching ePortfolio.  Here are some of the artifacts I would include:

1. Course design material
2. Lecture notes and/or accompanying learning materials for face to face courses
3. Module overviews and materials for online courses
4. Assignment instructions and rubrics
5. Examples of student work (with permission of course)
6. Informal and formal student feedback
7. Reflection (what went well, what could be improved, before, during and after course)

As Pelliccione and Dixon explain, the ePortfolio creation process includes multiple levels of reflection:

Selecting the artefact; Describing the contextual characteristics of the artefact; Analysing the choice of selection and how it demonstrates the outcome/standard; Appraising the appropriateness of the artefact in terms of how it relates to knowledge; and Transforming existing practice by identifying how the artefact will influence future practice. (p. 753)

When paired with self-reflection, the very act of curating my own teaching ePortfolio would be important in my professional development.
