I have the concept, screens, and brand direction for a new social network; what I need now is a skilled full-stack developer who can bring everything to life across Web, iOS, and Android. Scope The build covers a responsive website plus companion mobile apps that share a common back-end. Core features for the first release are already defined: rich user profiles, a real-time messaging system, and in-app notifications. I will supply wireframes and a feature backlog; your job is to turn them into production code, deploy the infrastructure, and ready the apps for the App Store, Google Play, and live web hosting. Key responsibilities • Architect and implement the back-end (database, authentication, REST/GraphQL API, push notifications). • Build the front-end UI for Web, iOS, and Android, ensuring a consistent experience everywhere. • Set up cloud hosting with CI/CD so each platform deploys from the same codebase or API. • Document the code, hand over a private Git repo, and run a short knowledge-transfer session. What I’d like from you • Links to at least one social or messaging project you’ve shipped. • A brief outline of the tech stack you recommend—React/Next + Node, Flutter + Firebase, or another approach that fits the brief. • A high-level milestone plan leading to MVP, closed beta, and public launch. Deliverables 1. Source code for back-end and all front-end clients. 2. Live production environment with CI/CD pipelines. 3. Build artifacts ready for App Store & Google Play submission. 4. Technical documentation and hand-over session. If this looks like the kind of end-to-end challenge you enjoy, let’s talk timelines and dig into the details.
