## About the Role

* Demonstrated custom animation work - organic motion or non-trivial visual effects beyond standard Animated API usage
 * Experience writing or integrating native iOS (Swift/Objective-C) and Android (Kotlin/Java) modules from a React Native project
 * Supabase or equivalent backend integration experience
 * In-app purchase implementation (Stripe, RevenueCat, or equivalent)
 * Push notification implementation (local and remote)
 * Comfortable working from a detailed written spec without design handholding
 * Experience designing object storage + CDN delivery for media assets in a production mobile app (e.g., S3 + CloudFront, Cloudflare R2, Supabase Storage, Firebase Storage) - able to recommend the architecture, not just wire up playback, * WidgetKit (iOS) or Jetpack Glance (Android) home screen widget experience
 * HealthKit or Health Connect integration
 * Core Haptics (iOS) or custom VibrationEffect (Android)
 * Experience with variable/display web fonts (e.g., Cormorant Garamond) in a native context
 * Familiarity with breathwork, wellness, or mindfulness app conventions

## Description

* Build a single React Native codebase targeting both iOS and Google Play from the existing Lovable front end and written spec
 * Stand up backend infrastructure: Supabase (auth, data), Stripe/RevenueCat (in-app purchases), push notifications (local + remote)
 * Integrate pre-generated narrated audio (11Labs-generated files) into each practice, syncing playback timing to on-screen content and breathwork pacing
 * Recreate custom animations already built on the front end (organic "diffuse color" pulse/heartbeat effect, milestone and ritual-completion animations)
 * Implement haptic feedback tied to practice pacing and completions
 * Architect and implement object storage + CDN delivery for a growing library of audio practices and ambient soundscapes
