StayMate
StayMate is a production-grade rental property marketplace that connects landlords with tenants. It features property listing management, search with filters, user authentication via JWT, real-time messaging, and image uploads — built with a clean separation between the Next.js frontend and Spring Boot backend.
Problem Statement
Finding rental properties in local markets often relies on fragmented social media posts and phone calls, lacking a unified search and communication platform.
