Custom WordPress plugin for automated event registration

A growing event management agency is urgently seeking a skilled developer to create a custom plugin for automated event registrations. The current manual process is causing significant delays and data entry errors, threatening the success of an upcoming major conference. The objective is to streamline the registration workflow entirely.

The developer will be responsible for building a robust plugin that integrates seamlessly with the agency's existing architecture. Key deliverables include:

• A dynamic front-end registration form with conditional logic
• Automated email confirmations with custom QR codes for ticket validation
• A comprehensive backend dashboard for managing attendees and exporting data

The chosen freelancer must deliver high-quality, secure code within a very tight timeframe. The final product must be fully documented and rigorously tested to handle sudden traffic spikes without performance degradation. Experience with complex database queries and external integrations is highly desirable for this critical assignment.
