I have made many complex database applications from scratch. One of which was a parade organizer. A very novel idea by the client. An application which helps to manage the hundreds of people who participate in a parade.

Create a new parade instance.

Use a custom parade link for public registration.

Gather required information for organizations signing up to the parade.

Parade admin can send bulk mails to parade organizations for announcements and parade information.

Add committee members and staff to the parade for facilitation.

Automated printable PDF's and QR code generation for delivery.

Mobile application for easy QR check-in to the parade.

Customize the parade settings per parade.

And much more.

The application has been working successfully for years now. Improving the lives of parade managers in various locations in the US.
