Overview

Estatein is a production-grade full-stack real estate platform that enables customers to browse, search, filter, save favourite properties, submit inquiries, and explore company content while providing administrators with a comprehensive CMS to manage listings, users, blogs, testimonials, customer communications, and business analytics from a single dashboard. The application follows a scalable modular architecture with server-side rendering, secure authentication, and production-ready engineering practices.

Problem

Many real estate businesses rely on disconnected systems, manually managed property data, limited search capabilities, and outdated administration workflows. Traditional solutions often lack scalability, analytics, secure authentication, and centralized content management, making it difficult to efficiently manage properties, customer inquiries, and business operations while delivering a modern user experience.

Solution

Built a production-ready full-stack platform using Next.js 16, Express 5, TypeScript, and MongoDB with a modular layered architecture. The application provides advanced property discovery, role-based dashboards, secure JWT authentication, server-side rendering, Cloudinary media management, analytics reporting, and a fully data-driven admin CMS that allows the entire website content to be managed without modifying frontend code.

Architecture

Designed a decoupled two-tier architecture consisting of a Next.js 16 frontend and an Express 5 REST API communicating through a same-origin proxy, with the backend following a modular layered architecture (Router → Middleware → Controller → Service → Model) to ensure clear separation of concerns, reusable business logic, centralized error handling, role-based authorization, validation middleware, and standardized API responses, while public pages leverage Server Components for SEO and performance, and authenticated requests use secure JWT access tokens with httpOnly refresh cookies.

Database Design

Designed a scalable MongoDB database using Mongoose with optimized schemas, relationships, indexes, and reusable models. The database includes collections for users, properties, categories, blogs, testimonials, reviews, inquiries, favorites, contacts, newsletters, uploads, and analytics. Implemented text indexes for property search, compound indexes for optimized filtering, automatic slug generation, nested document structures for property specifications, and aggregation pipelines for dashboard reporting.

API Design

Developed a RESTful API following consistent response contracts (ApiResponse / ApiFailure) across more than thirteen feature modules. The API includes JWT authentication, refresh token management, role-based authorization, request validation with Zod, centralized error handling, pagination, sorting, filtering, analytics endpoints, image upload pipelines, and standardized CRUD operations. Every endpoint follows predictable response structures, making frontend integration reliable and maintainable.
