Nature of work
no kras
Vague JD — no KRAs present to derive a specific nature of work.
Tech stack maturity
Mainstream Modern
The stack centers on iOS development with Swift, Xcode, Core Data, and push notifications, which are established, widely used modern mobile technologies rather than bleeding-edge or legacy-pre-cloud.
