I’m building a cross-platform social media application that will let users create rich profiles, chat in real time, and scroll an algorithm-driven news feed. The front end is planned in React; on the server side I’m open to Python (FastAPI or Django), .NET, or Java—whichever lets you deliver clean, well-documented RESTful APIs quickly. Beyond the core features, I want to embed an AI-powered chatbot that can handle basic customer-support questions inside the app. If you already work with frameworks such as TensorFlow, PyTorch, or Azure Cognitive Services, that experience will be valuable. I’ll handle UI mock-ups and brand assets; you’ll translate them into responsive components, wire them to the backend, and integrate the chatbot so it feels native. I prefer collaborating with developers based in Europe, Asia, Africa, or Australia to keep time-zone overlap manageable. Deliverables • React codebase with reusable components and state management • Back-end services (Python / .NET / Java) with unit tests and API documentation • AI chatbot module connected to our support knowledge base • Deployment scripts for staging on AWS or Azure I review work in milestones: first the profile flow, then messaging, then the news feed, and finally the AI layer. Clear git commits and short demo videos at each stage will keep us in sync and help me sign off quickly.
