Full-Stack Developer: Social Matching App (Web/iOS/Android)

We are building a mobile social networking platform that connects users and businesses based on shared interests and preferences. The application will feature a freemium subscription model, enabling users to discover like-minded individuals, explore local businesses, and identify new opportunities within their communities. Businesses will gain access to a powerful local marketing and networking tool to expand their reach and connect directly with target users. The platform incorporates an advanced matchmaking algorithm that analyzes user parameters and preferences to surface compatible profiles and nearby businesses, leveraging a six-degrees-of-separation model for intelligent connections. Core features include user profiles, connection requests, direct messaging, file/media sharing, group chat, video calling, group creation and management, content posting, and community engagement tools such as likes, comments, and shares. The project is approximately 25-30% complete. We are seeking a full-stack developer to build the remaining web application, iOS, and Android components with enterprise-grade security and a seamless user experience. This is a fixed-price engagement valued at $11,000 for US-based contractors.
