## Declared gaps

Stated explicitly so they are not inferred incorrectly: no native iOS (Swift) development; iOS is
reached through Kotlin and Compose Multiplatform. No commercial Flutter or React Native delivery.
No production LLM, RAG or agent product; AI experience is production computer vision and OCR plus
daily use of AI coding agents. Backend work is limited to supporting Node.js endpoints.
