...the back-end and PostgreSQL as the data store. Core features I need from day one are: photo and video sharing (upload, display, feed), real-time direct messaging between users, and rich user profiles with avatar, bio and basic follow / unfollow mechanics. For authentication I only need a solid email-and-password flow right now, but the codebase should be organised so that OAuth providers can be slotted in later without a full rewrite. Please structure the project as a modern SPA: React (hooks, context or Redux if you prefer), responsive UI, lazy-loaded media, and clean routing. The server may use Express or a comparable Node framework, expose a REST or GraphQL API, handle file uploads to local storage or S3, and push chat updates via WebSocket or Socket.io. PostgreSQL...

We are a financial service company looking for an experienced Full-Stack Developer or a small team to deploy our pre-built React-based Loan Management System, migrate its data layer from Firebase/Mock to a robust SQL Database (MySQL or PostgreSQL) with a secure Node.js backend, and build 2 companion Android apps that sync with this centralized database. The web portal's user interface, screens, states, and business logic are 100% complete and built in React (TypeScript) + Tailwind CSS + Vite. You only need to build the SQL backend, wire the API endpoints, build the Android applications, and go live on our custom domain.
