I’m launching a worldwide singles fraternity—“Grupo Honest Singles”—designed to connect genuine people while giving special visibility and support to carefully selected owner-operator businesses. To make this vision accessible everywhere, the community needs to live both on the web and on mobile. The build covers a responsive website plus companion apps for iOS and Android that mirror the same core experience. Members should be able to create rich profiles, search and interact with one another, and discover businesses we endorse through a dedicated support section. Security and ease of entry matter, so the platform must allow account creation and sign-in through standard email/password as well as popular social logins. Key deliverables • Fully branded website, mobile-friendly from day one • Native or cross-platform apps for iOS & Android published to their stores • Unified back-end and admin dashboard for user, content, and business partner management • Dual authentication system (email/password + social) with best-practice security I already have high-level content and branding assets; the next step is translating them into a polished, scalable product. Include in your proposal the tech stack you favour (React, Flutter, Firebase, etc.), the development timeline you foresee, and any live examples of similar community or marketplace work.
