Why the collective stays small on purpose

Devlink Webdev began when three release engineers kept rewriting the same onboarding deck for squads in Kyushu and Kansai. We turned those decks into repeatable repos, then into courses where every exercise ships with mentor commentary instead of anonymous autograding.

We are not a marketplace of thousands of videos — we maintain a narrow catalog so Git history, review tone, and release storytelling stay coherent across modules.

Principles we argue about in Slack

  • Teach with diffs learners can reopen months later.
  • Prefer explicit trade-offs over “best practice” slogans.
  • Design cohorts that respect Golden Week and EU summer quiet.
  • Keep pricing boringly transparent — surprises belong in fiction, not invoices.
