Rehla

Rehla is a comprehensive travel reservation and management platform designed for travel agencies and their clients. Agencies use a web dashboard to manage trips, reservations, clients, employees, and finances, while clients use a native mobile application to discover, compare, and book trips. The platform was built as a modern TypeScript monorepo with a strong focus on type safety, security, usability, and clear separation of responsibilities across the system.

The Problem

Travel agencies often need to coordinate several interconnected workflows, including trip scheduling, reservation management, client information, employee access, pricing, payments, cancellations, and financial reporting. Managing these workflows across disconnected tools can make day-to-day operations harder to maintain and increases the likelihood of errors.

Rehla was created to bring these workflows into one platform. The system provides agencies with a centralized management dashboard while giving clients a dedicated mobile experience for browsing trips, making reservations, and completing payments.

Goals and Objectives

The main goal was to create a complete travel management platform that could support both the operational needs of travel agencies and the booking experience of their clients.

• Provide agencies with a centralized system for managing trips, reservations, clients, employees, and finances.
• Provide clients with a simple mobile experience for discovering and reserving trips.
• Integrate payment processing for reservations, refunds, and automatic withdrawals through Paymob.
• Protect sensitive information such as national IDs using root-password-based end-to-end encryption.
• Maintain strong type safety and separation of concerns across the frontend, backend, domain, and database layers.
• Make the system accessible to users with low technical literacy through detailed bilingual documentation.

Development Process

The project was developed as a multi-part monorepo using TypeScript, with the system divided into separate applications and domain packages. This structure made it possible to keep the agency dashboard, client mobile application, APIs, business logic, and database layer independently organized while still sharing contracts and utilities.

The architecture follows domain-driven design with clear boundaries between the admin, client, and core domains. The API layer uses oRPC contracts and Hono on Cloudflare Workers, allowing the frontend and backend to share types and validation rules throughout the application.

The agency side was developed as a React web application with features for managing trips, reservations, clients, employees, analytics, and financial reports. In parallel, a React Native application built with Expo was developed for clients, providing trip discovery, filtering, reservations, authentication, and payment functionality.

Payment processing was integrated with Paymob to support reservations, refunds, and automatic withdrawals. Sensitive national ID information was protected using end-to-end encryption, with encryption rooted in a password controlled by the system administrator.

Since the platform is intended for real operational use, documentation was treated as part of the product rather than an afterthought. A detailed 70-page manual was created in both Arabic and English, explaining every major feature and button in the system and making the platform easier to use for people with limited technical experience.

Architecture

Rehla is organized as a monorepo with a clear separation between applications, APIs, domain logic, and persistence. The core codebase contains nine workspace packages, covering the agency web dashboard, client mobile application, API layers, domain layers, and database access.

The architecture uses contract-first APIs, feature-based organization, end-to-end type safety, and shared domain primitives. Cloudflare Workers provide the backend runtime, while PostgreSQL with Prisma is used for relational data storage. Cloudflare R2 is used for object storage, and Expo EAS is used for mobile application deployment.

Results

Rehla has developed into a complete travel management platform that covers the operational workflow of an agency as well as the customer booking experience. The current system supports trip management, reservations, payments, client management, employee access control, analytics, financial reporting, and secure handling of sensitive information.

In addition to the software itself, the project includes a bilingual user manual and a professional 20-slide presentation containing mockups and screenshots of the platform. These materials were created to make the system easier to present, understand, and adopt.

Key Features

• Trip management: Agencies can create, edit, schedule, and manage trips with complete CRUD functionality.
• Reservation management: Agencies can manage reservations and monitor their status throughout the booking lifecycle.
• Client management: Agencies can maintain detailed client records and manage customer information from one place.
• Employee management and RBAC: Agencies can manage employees and control access to different parts of the system according to their roles.
• Group pricing and discount codes: Flexible pricing tools support group-based pricing and promotional discounts.
• Financial reports: Agencies can track financial activity through analytics and detailed reports.
• Paymob integration: The platform supports payment processing, refunds, and automatic withdrawals through Paymob.
• Client mobile application: Clients can browse and filter trips, create reservations, manage their profiles, and complete payments through a native React Native application.
• Automatic reservations: The client booking flow connects reservation creation with payment processing, reducing the amount of manual work required from agencies.
• End-to-end encryption: Sensitive national ID information is encrypted using a root-password-based encryption system.
• Audit logging: Important actions are tracked to improve accountability and operational visibility.
• Google OAuth authentication: Users can authenticate through Google while the platform maintains separate access flows for different parts of the system.
• Bilingual documentation: A 70-page manual in Arabic and English documents the system's features and interface in detail.

Conclusion & Learnings

Building Rehla provided experience with designing and maintaining a large-scale TypeScript monorepo across web, mobile, backend, domain, and database layers. The project required more than implementing individual features, with particular attention given to architecture, API contracts, security, payments, documentation, and the interaction between multiple applications.

The project also reinforced the importance of designing software around its users. The bilingual manual, simplified client experience, and separation between agency and client applications were all built around making the system easier to understand and operate in practice.
