Build Social Network Platform

Build a web-based social network that combines real-time video calling, group conferencing, instant messaging, content creation, and unified notifications. The platform should support English launch and easy expansion to major languages. We need a modular architecture with a clean, documented codebase ready for handoff. Deliverables include the full platform, admin dashboard for users, content, and language management, private source code with setup instructions, deployment scripts, basic monitoring, and post-launch support for critical fixes. Please share relevant examples of similar work.
