I was brought in to complete and optimize a matchmaking and messaging application - taking the project from a partially built prototype to a polished, production-ready release. I worked across the full stack - from backend database setup and real-time features to frontend integration and deployment - ensuring the app was secure, scalable, and ready for the App Store.

Authentication & Onboarding: Refined signup and login flows, implemented persistent session management, and improved the onboarding UI for a smooth user experience.

Database & Schema Setup: Finalized the database architecture for users, matches, messages, and media assets. Configured Row Level Security (RLS) and optimized queries for speed and reliability.

Real-Time Messaging & Notifications: Built a robust chat system with WebSocket-based subscriptions, typing indicators, reactions, and instant match notifications — all synced across devices.

Media Uploads & Matching Logic: Integrated secure photo uploads with caching and optimization, and completed the compatibility-based matching algorithm with like/pass functionality.

Frontend Integration & UI Enhancements: Connected the backend logic to the existing frontend, optimized component rendering, and improved user feedback states throughout the app.

Production Readiness & Deployment: Configured the production environment, applied performance tuning, and assisted with App Store/TestFlight deployment.
