Smart Locker System with Mobile Integration -- 2

I'm looking to develop a smart locker system that interfaces with a mobile app on both iOS and Android platforms. The lockers are designed for user-item interaction, where a user deposits an item and inputs their phone number. An OTP (One-Time Password) is generated and sent via SMS. The user then inputs this OTP at the locker system, which will unlock if the OTP matches.

Key Features:
- Smart locker with mobile app integration
- OTP generation and SMS sending
- Locker unlocking based on OTP verification

The mobile app should also incorporate:
- Notifications for successful OTP entry
- A history log of item deposits and pickups
- User profile management

Ideal Skills and Experience:
- Proficiency in iOS and Android app development
- Experience with smart locker systems
- Knowledge in SMS API integration
- Skills in implementing user notifications and history logs in apps
- Prior work in creating user profile management systems in apps.
