Hessah (حصّة) – Real Estate Investment Platform

Hessah is a real estate investment platform that enables users to explore investment opportunities, manage portfolios, and track transactions across both web and mobile applications.

My role focused on designing and implementing the backend services and API contracts that ensure consistent data flow between the web platform and the Flutter mobile application.

To support parallel development across multiple clients, I structured the backend with stable REST API contracts, predictable versioning strategies, and well-defined domain models for investment portfolios, transactions, and user accounts.

Key Features

• Cross-platform REST API architecture for web and Flutter clients

• Structured investment domain modeling for portfolios and transactions

• Consistent API response contracts to prevent integration conflicts

• Version-aware backend design to support iterative feature development
