Multilingual PropTech Platform: Resilient CRM & Agent App

Solution overview

The Real Estate Platform v12 provides a unified ecosystem across three distinct interfaces, all powered by a single, resilient database. It features a public-facing website for property search, booking, and payments, a powerful Filament admin panel for CRM and operational management, and a Flutter-based 'Synergy Agent' mobile application for field agents.

Public WebsiteMultilingual property search, booking, payments & blog

Filament Admin PanelComprehensive CRM, calendar, transactions & content management

Synergy Agent AppFlutter app for agents to manage deals, bookings & properties on-the-go

Booking & Payments ModuleHandles seasonal pricing, Stripe, PayPal & offline transactions

Mobile APISecurely syncs data for the Flutter agent application

Product experience & design

The platform offers a streamlined user journey across its interfaces. The public website provides an intuitive search and booking experience, complemented by a blog and an AI chat assistant. The Filament admin panel features a customizable Page Builder for content, a deal pipeline for CRM, and robust user role management with 2FA for super-admins. The Synergy Agent mobile app, built with Flutter, provides a consistent experience across Android, iOS, and Windows, allowing agents to manage properties, bookings, deals, and receive instant FCM alerts directly from their devices.

Data & architecture

At its core, the system relies on a MySQL database, carefully managed to ensure resilience with legacy schemas. The architecture is layered, separating client interfaces (Public Web, Mobile API, Filament Admin) from the Laravel application logic (Web Routes, Sanctum API, Services Layer, Eloquent Models). Key entities include PROPERTY, BOOKING, CLIENT, DEAL, TRANSACTION, PAGE, and USER, with over 33 Eloquent models supporting soft deletes and content translations. The critical path for booking involves a sequence from visitor booking submission, saving pending status in MySQL, payment processing via Stripe or PayPal, webhook confirmation, and finally updating the paid status and sending a guest link.

Technical delivery

Built on Laravel 12 and PHP 8.2+, the platform leverages Filament 5 for rapid admin panel development, Flutter for cross-platform mobile, and MySQL as the database standard. Key integrations include Stripe and PayPal for international payments, Spatie packages for media optimization (WebP) and backups, and Firebase Cloud Messaging (FCM) for mobile push notifications. Deployment on Hostinger production environments was carefully managed with custom deploy:repair-schema commands to handle legacy database inconsistencies without data loss, alongside unified deploy:post-deploy scripts for cache management and admin:ensure-user for admin access recovery. Security features include mandatory 2FA for super-admins, API throttling, and PHPUnit feature suites for testing.

Omar's contribution

As a full-stack developer, I led the architecture, development, and deployment of this platform. My contributions spanned the entire stack, including designing the Laravel 12 backend, implementing the Filament 5 admin panel, developing the Flutter mobile API and agent application, integrating Stripe and PayPal payments, and setting up resilient Hostinger DevOps practices, particularly the deploy:repair-schema tooling for safe legacy database management.
