Matrimonial Matchmaking Website Build -- 2

I need a fully scalable, security-first matrimonial platform built from the ground up. Core user flow covers profile creation and matching, a real-time messaging system, and robust search & filter options. On top of that, the site must include video calling, an integrated payment gateway, and AI-driven matching logic. Also including Android app and ios app building Performance matters as much as features: please architect a cacheable database layer so the site stays fast as the user base grows. Clean code, penetration-tested endpoints, and cloud-ready deployment scripts are all expected. In replication and ha environment. Deliverables • Responsive web app (front-end + back-end) ready for production • Secure authentication, profile management, and match algorithm • Messaging, video calling (WebRTC or equivalent), and payment integration • AI matching module with straightforward training data hooks • Caching strategy documented and implemented • Deployment guide plus minimal CI/CD pipeline so updates roll out safely ai based machine-learning recommendations :-hybrid approach regional expansion with regional language
