Arabic-Speaking Full-Stack Developer

We are looking for an Arabic-speaking Full-Stack Web Developer to complete and professionalize an existing platform for selling interactive educational activities and classroom games to teachers. The e-commerce store, payment, and checkout are already handled through Zid. The main work is to review and improve our existing web-based educational activities, make them responsive and production-ready, and build a scalable backend system that allows us to easily manage activities and upload/update question banks without modifying the code each time. The project also requires a secure access/licensing system so that after purchasing an activity, each customer receives access through a unique link/code with configurable usage or device limits to reduce unauthorized sharing. We already have several working activity prototypes and existing source code, so this is not a project to build everything from scratch. Arabic communication is required, as the platform and all educational content are primarily in Arabic.
