Portfolios that mention failure modes get better reviews

A polished UI screenshot tells us less than a paragraph about a migration that almost locked a table. We ask learners to keep a small incident log alongside screenshots so mentors can comment on sequencing, not just color choices.

The second paragraph focuses on tests. We reward pull requests that add failing cases before fixes, even if the UI barely changes. That habit travels into API courses where consumers depend on predictable error shapes.

Finally, we discuss narration. A portfolio should read like a field note: assumptions, constraints, and the next risk you would tackle with another week. That tone matches how internal reviewers read documentation when operational incidents happen.
