Pet dating App & community

Built a production-grade pet dating ecosystem consisting of a high-performance Node.js/Prisma backend, a glassmorphic Next.js admin panel, and a feature-rich React Native mobile app. The core innovation is a relational configuration engine that controls platform features, usage limits, and tier-based permissions dynamically without code changes.

The challenge

Many social apps struggle with rigid monetization models and administrative overhead. We needed a system that offered extreme flexibility—allowing admins to toggle features (like Rewind, Super Like, or AI Assist) and adjust usage quotas (swipes, storage) per user tier in real-time, while maintaining sub-50ms API response times.

How I approached it

• →Interceptive Middleware: Developed a high-performance "FeatureGate" service in Express that intercepts every request to validate permissions and quotas via Redis-cached tier configurations.
• →Data-Driven Architecture: Designed a complex PostgreSQL schema using ULIDs for scalability, handling everything from geofenced matching to multi-currency IAP transactions.
• →Real-time Engine: Wired up Socket.IO with Redis adapter for horizontal scaling, powering instant messaging, typing indicators, and live match notifications.
• →Admin Backoffice: Built an 18-module administrative dashboard in Next.js 16 with real-time analytics, content moderation workflows, and a granular RBAC system for staff.
