Innovative Raffle Platform Development

I'm looking for a developer to create a unique raffle platform where users can win physical prizes multiple times a day. It’s crucial to maintain the platform's integrity through measures like preventing multiple accounts.

Key Features Needed:
- User registration and login
- Automated raffle drawing
- Winner announcement and notification

The ideal candidate should have:
- Experience in developing secure user authentication systems
- Strong background in automated processes for games and raffles
- Knowledge in notification systems

Ability to ensure platform integrity is crucial.
