Build Multiplatform Chat Companion

I’m creating an “online rental boyfriend” experience where the sole focus is real-time chat companionship. The service must be accessible across the three channels I rely on most:

• Website
• Mobile app
• Social media integrations

Your job is to set up the actual chat layer—user registration, profile management, secure messaging and presence status—so clients can hop in and start a private conversation with their chosen companion from any of the outlets above. A consistent look-and-feel is important, but I’m happy to hear framework recommendations. React (web) plus React Native or Flutter (mobile) and a Node.js/WebSocket backend are all fine; if you have a better stack that still delivers latency-free messaging, pitch it.

Key expectations
• Single code-base or well-documented API so each platform stays in sync
• End-to-end encryption or another proven security approach for personal data
• Admin dashboard where I can add or suspend “boyfriend” profiles and monitor active chats
• Analytics hooks so I can track usage and session length

I skipped the feature list earlier, so feel free to propose extras—voice notes, video snippets, in-chat gifts, anything that keeps users engaged—as optional add-ons I can toggle later.

Please outline your proposed stack, milestone plan, and estimated turnaround time when you bid.
