LinkNest: Multi-Tenant Digital Identity & Privacy-Preserving Contact Hub
Multi-tenant link-in-bio SaaS with privacy-preserving contact requests and Supabase Row Level Security.
A multi-tenant digital profile and link management SaaS platform evolved from the single-user rukon-link architecture. Designed to give professionals and creators a unified digital presence without compromising privacy. Features a strict link hierarchy (1 Highlighted Super Link + 5 Standard Links), an administrative approval workflow for extra link quotas (+1 to +3), and a privacy-preserving contact exchange system where phone numbers and emails are never exposed publicly. Visitors submit structured contact requests, which creators can approve and convert into direct WhatsApp conversations using pre-configured international dialing codes (+60 Malaysia, +880 Bangladesh). Built with Next.js 16, React 19, TypeScript, and Supabase PostgreSQL with strict Row Level Security (RLS).
Complete full-stack architecture: Next.js 16 App Router, multi-tenant Supabase schema with RLS, WhatsApp bridge, and quota management.
