Thani Promotion

We are looking for an experienced Full Stack SaaS and Android Developer or development team to build **THANI Promotions**, a cloud-based digital advertising platform for restaurants and hospitality businesses. Our goal is to provide restaurants with rechargeable Android-powered tabletop digital displays that continuously show promotional images, videos, daily specials, happy-hour deals, and advertisements. We need a complete software solution consisting of a **THANI Super Admin Dashboard** to manage restaurants, subscriptions, users, and devices; a **Restaurant Owner Dashboard** where businesses can upload images and videos, create playlists, schedule promotions, and publish advertisements to selected devices; a **secure cloud backend** to manage restaurant accounts, media storage, device registration, synchronization, and monitoring; and a **native Android application** that automatically downloads and plays advertisements in full-screen kiosk mode. The Android application must support offline playback, automatic synchronization when internet connectivity returns, automatic startup after device reboot, crash recovery, local media storage, and remote device monitoring. Our preferred technology stack is **Angular, TypeScript, Java, Spring Boot, PostgreSQL, Kotlin, Android SDK, Media3/ExoPlayer, and AWS**. The platform must support multiple restaurants with secure data separation, reliable device communication, and scalable cloud infrastructure. We will source Android tabletop hardware from third-party manufacturers, and the developer must ensure software compatibility with the selected devices. We expect a complete, secure, reliable, production-ready SaaS platform, including frontend, backend, Android application, cloud deployment, testing on actual hardware, technical documentation, and full source code ownership. Experience in digital signage, Android kiosk applications, offline-first systems, IoT device management, and multi-tenant SaaS development is highly preferred.
