Real Estate & Property Management

Build me a complete in-house property management ERP that runs properties, units, owners, tenants, contracts and payments in one place, with a dashboard in English plus Arabic RTL support. Give every employee a role and fine-grained permissions (RBAC): general manager, accountant, collections officer, maintenance supervisor, with secure login, two-factor authentication and an audit log of every change to a contract or a payment. Design the database indexed on contract and unit numbers and partitionable by property portfolio, with caching for repeated reports and task queues (queues) for generating the heavy monthly statements so the interface never slows down. Add a full security layer: encryption of sensitive data, rate limiting, protection against injection and common web attacks, and automatic daily backups. Connect e-invoicing compliant with the tax authority (ZATCA) so that every contract or payment generates a compliant invoice, and add income, expense and occupancy-rate reports per property with Excel/PDF export. Add monitoring and analytics (observability) and performance logs, and deliver the system production-ready with a professional user experience, tests and concise documentation. The code and the data are entirely mine, with the option to connect a GitHub account.

Build me an online portal facing tenants (a website plus an installable PWA) where the tenant signs in to a secure account to see their contract, invoices and payment history and pay the rent online. Connect payments to mada, Apple Pay and Moyasar or HyperPay through API keys stored in the secrets vault, with an electronic receipt and a ZATCA invoice after every payment. Add clear permissions (RBAC) separating the tenant from the unit owner from property management, and secure login by mobile number (OTP over SMS). Make it English-first with Arabic RTL support and full accessibility, and design it to handle thousands of concurrent tenants through an indexed database, caching of contract pages, and a task queue for sending notifications and receipts. Add a security layer: encryption, rate limiting, protection against common web attacks, and backups. Add monitoring and analytics to track successful and failed payments, and deliver it production-ready with a smooth experience, tests and concise documentation.

Build me an automation engine (a system that runs by itself in the background) that handles renewal reminders, collections and overdue follow-up for tenants with no manual intervention. Base it on scheduled jobs that check contracts and payments daily and fire WhatsApp and SMS messages at set moments: a renewal reminder a configurable period before the contract ends, a collection reminder before the due date, and a graduated follow-up sequence after it's late. Connect WhatsApp and SMS through API keys in the secrets vault, and use a task queue with retry logic on send failure so the system handles tens of thousands of messages without losing a single one. Record the status of every message (sent, delivered, replied to) in a tracking dashboard, with permissions (RBAC) defining who can edit message templates and schedules. Add rate limiting to avoid being blocked, encryption of customer phone numbers, and backups. Add monitoring and analytics of response and collection rates after each reminder campaign, and make it English-first and production-ready with tests and concise documentation.

Build me a mobile app (Expo, running on iOS and Android) for marketing property development projects and showing units to interested buyers, with search and filtering by city, area, price and unit status (available/reserved/sold). Show each unit with its photos, floor plan and map location, and add a button to book a viewing that records the lead's details straight into my system and sends an automatic confirmation by SMS or WhatsApp. Serve project images through a content delivery network (CDN) for fast loading, and keep search indexed in the database so it handles thousands of concurrent visitors, with caching of unit listings. Add an admin dashboard for the team with permissions (RBAC): a marketer who adds units, and a salesperson who follows up leads and appointments. Make it English-first with Arabic RTL support and full accessibility, with security (encryption, rate limiting, protection against common attacks) and backups. Add analytics for views and bookings per unit, and deliver it production-ready with a professional experience, tests and concise documentation. The code is entirely mine.

Build me a multi-tenant cloud real-estate platform (multi-tenant SaaS) that serves several property management companies under one roof, and design it architecturally to scale to millions of users. Isolate each company's data (tenant) logically, with a database indexed and partitioned (sharding/partitioning) by tenant and region, a caching layer for repeated queries, and task queues (queues) for every heavy operation such as bulk invoice generation, account statements and reminder campaigns. Serve static assets and images through a content delivery network (CDN), and design the services to withstand high load with load balancing. Apply hierarchical permissions (RBAC) at the platform level and within each company, with secure login and two-factor authentication. Connect payments (mada/Apple Pay/Moyasar), e-invoicing (ZATCA) and WhatsApp independently per tenant through API keys. Add a comprehensive security layer: encryption in transit and at rest, per-tenant rate limiting, protection against common attacks, and backups with disaster recovery. Add monitoring, analytics and centralised logs (observability) to follow performance and failures. Make it English-first with Arabic RTL support and accessibility, and production-ready with tests and concise documentation.
