I need a fully-functioning video-sharing and streaming site that captures the core YouTube experience and is ready to demo in just two weeks. The first phase is capped at US$500; deliver a rock-solid result on time and we can transition into a long-term, full-time arrangement. Scope for this sprint • User account creation and management with secure sign-up, profiles, and basic channel controls. • Video upload, server-side transcoding, and adaptive playback (HLS or DASH). • Commenting system with threaded replies, likes, and simple moderation. • Live-streaming capability via WebRTC or RTMP ingest routed through an open-source media server (Nginx-RTMP, Ant Media, etc.). • Fast, accurate search across titles, descriptions, and tags. • Mobile-first, responsive UI that feels familiar to everyday YouTube users. Preferred tech direction React or Vue on the front end, Node.js or Django for the API, PostgreSQL/MySQL as the data store, and S3-compatible object storage fronted by a CDN for smooth delivery—but I’m open to your proven stack if it ships on time and within budget. Acceptance criteria 1. All features above work end-to-end on a public staging server I can access. 2. Page load and video start times stay under three seconds on a typical broadband connection. 3. Clean, well-commented source code is delivered via Git. 4. A concise deployment guide lets me reproduce the environment on my own VPS. When you reply, outline your chosen stack, how you’ll tackle transcoding and live streaming, and link to one or two similar builds you’ve completed.
