I need a full-stack, SaaS-ready solution that lets residents, committee/admin members and security guards handle all daily society tasks from their phones while I oversee everything from a web dashboard. Core workflow • Users sign in with mobile-number OTP and see only the screens tied to their role (Resident, Admin, Guard). • The mobile build must run smoothly on both iOS and Android, using a single codebase if that speeds things up. • A clean top navigation bar should guide every screen transition. Key modules Visitor Management – residents can pre-approve guests; guards simply scan/enter details at arrival and departure; both sides get immediate status updates. Complaints – residents file an issue, watch it move from Open → In Progress → Resolved, and rate the outcome. Notice Board – admins post news or emergency alerts that land instantly on every relevant device. Dashboards – quick snapshots for residents (personal activity, pending items) and a richer console for admins (all societies, analytics, user roles). Real-time alerts required • Push notifications • SMS alerts Multi-society architecture Each society must sit in its own isolated data space, so one codebase but fully segregated tenants—ideal for onboarding new communities without extra deployments. Deliverables • Cross-platform mobile application (iOS & Android) • Web-based admin panel • Secure, well-documented REST/GraphQL APIs • Complete, clean source code with basic setup documentation Code quality, role-based security, and performance across low-end Android phones are essential acceptance criteria.
