During the development of EstateHub, we faced several technical challenges, particularly optimizing complex property filtering without slowing down WordPress due to heavy meta queries. Avoiding bulky third-party real estate plugins meant building custom plugin architecture, shortcodes, and query logic entirely from scratch. Integrating dynamic filters with Elementor’s custom query hooks required careful manipulation to prevent layout conflicts and caching issues. Implementing a secure login workflow demanded proper validation, session handling, and role-based access control. Additionally, ensuring reliable email delivery for inquiries and appointment bookings required structured sanitization and seamless integration with WordPress mailing functions while maintaining overall site performance as listings scaled.
