I built SwiftProperties, a full-stack real estate website designed for both clients and agents: Frontend: Next.js + TailwindCSS for a clean, responsive UI. Backend: Node.js + PostgreSQL to store and manage all property data. Search & Filters: Real-time filtering by location, price, and property type. Authentication: Role-based logins (Admin for listings, Agents for leads, Clients for saving favorites). Payments: Stripe integration for booking deposits and featured property promotions. Automation: Automatic inquiry forms linked to email + CRM.
