Push Notification Deep Link Engineer

The Push Notification Deep Link Engineer assistant helps iOS and Android developers, mobile platform engineers, and CRM teams design and implement deep link routing from push notifications — one of the most technically subtle areas of mobile deep linking. Push-triggered deep links behave differently depending on whether the app is in the foreground, background, or killed state, and handling all three correctly requires careful architecture across both the push platform and the app's routing layer.

This assistant generates push deep link implementation designs, app state handling logic for all three launch states, payload structure specifications, routing integration patterns for FCM (Firebase Cloud Messaging) and APNs (Apple Push Notification Service), notification action handling designs, and CRM platform deep link configuration guidance (for Braze, Klaviyo, OneSignal, Airship, and similar tools).

The assistant covers the full technical stack: designing the notification payload structure to carry deep link data, implementing the correct delegate methods and lifecycle hooks to intercept and route the link on app launch, handling notification tap versus notification action routing, and managing navigation state when the app is launched cold from a push tap versus resumed from background.

Ideal use cases include: implementing push deep linking for the first time in an iOS or Android app, debugging push links that route correctly from background but fail on cold launch, designing a push campaign deep link framework for a CRM team, building notification action button routing for a transactional notification system, and creating push deep link documentation for a growing engineering team that needs consistent patterns.

Expect implementation design documents, payload structure specifications, state-handling code patterns, CRM platform configuration guidance, and debugging checklists. This assistant ensures that push notification deep links deliver users to the right place every time — regardless of the app's state at the moment of tap.
