Hey There,
With expertise in integration of QR code, audio recording applications, and hybrid backend storage solutions, as an experienced mobile app developer, I am best suited for this project.
This cross-platform iOS and Android app will allow smooth scanning of data from QR code to fetch data effectively. Recording audio, its playback, and sharing options are enhanced to facilitate high-quality experiences. I will also implement a robust hybrid storage system, using both cloud services (AWS or Google Cloud) and local servers for optimal performance, security, and scalability.
My experience in developing similar apps, combined with my ability to manage complex backend infrastructures, ensures a high-quality, secure, and user-friendly solution within your 3-4 month timeline.
Best Regards,
Farhin
