Corporate Event Management & Photo Publishing Site

I need a web platform to manage corporate events and publish photos with mixed access - some sections public, and others restricted.

Key Requirements:
- Connect to Salic, to get all projects associated to an proponent
- each project should have a public site with some information
- Event Management: This site should facilitate the management of our corporate events, related to projects. Each project can have more than one event, each event can be accessed with one or more specific sponsor.
Features should include:
- Event Registration: Users should be able to receive information for events they are sponsor
- Calendar Integration: The site should sync with popular calendar applications for seamless planning.
- Invitation Management: A system to manage invitations to each event is essential.

- Access Control: The site will have mixed access. Some sections will be public, while others will be restricted and require a login.

Ideal skills for this project include web development, Nextjs, Type script, and knowledge in setting up secure login systems.
