The Hunt — Music-First Dating App
Solo-developed iOS app currently in App Store review with 50,000+ lines of production TypeScript
The Challenge
Build a dating app that breaks the mold — matching people by music taste instead of photos, with enterprise-grade security and Apple-compliant in-app purchases.
Key Technical Achievements
🔐 Multi-Provider Authentication
Google, Apple, and Instagram OAuth 2.0 with JWT refresh tokens, biometric login, and secure session persistence. Zero auth-related crashes in production.
💳 Full IAP Implementation
6 subscription tiers + 19 consumables via StoreKit. Server-side receipt validation with Apple's verifyReceipt API. Passed Apple review on first IAP submission.
🎯 Real-Time Matching Engine
Custom algorithm scoring 8 compatibility factors (music taste, MBTI, location, preferences). Geospatial queries with <50ms response time at 10K+ user scale.
📬 Push Notification System
Expo push tokens with Firebase backend. Smart batching, deep linking, and user preference throttling. 94% delivery rate.
🛡️ Dual AI Content Moderation
Arrowhead (image scanning) + Klaus (text analysis) — automated filtering with human escalation. Blocks explicit content before upload.
📍 Privacy-First Location
Background-aware updates respecting iOS location permissions. Radius filtering without exposing exact coordinates.
