Prove organizational leverage beyond team management - Mention company-wide migrations, RFC process adopted by 14 teams, partnership with CTO, open-source contributions to show you shape how the organization operates.

Name platform-level architectures you own - Reference internal developer platform, multi-cloud control plane, infrastructure abstraction layer, compliance automation engine to prove you define company technical direction.

Lack of people development outcomes - Not showing promotion pipeline (promoted 7 engineers), hiring influence, org design contributions, or engineering culture impact misses a core principal responsibility.
