I serve as the lead architect for "Music Near Me," a real-time event discovery and studio booking platform for the music industry. Originally built on FlutterFlow and Firebase, I spearheaded the complete migration to a custom full-stack Flutter mobile application with a Supabase back end and a Next.js administrative portal.

The migration was driven by the need for complex relational data handling and specialized geospatial queries that exceeded the capabilities of the original low-code setup. I architected the new system to leverage Supabase’s PostgreSQL capabilities for real-time venue availability and event synchronization. On the front end, I developed a highly responsive Flutter app for iOS and Android, ensuring seamless map integration and low-latency performance. On the business side, I built a robust admin dashboard with Next.js to enable venue owners to manage high-concurrency booking schedules. This refactor significantly improved app performance, data integrity, and scalability across multiple regions.
