Build Small Web Feature: Spotify Sync + Chat (Web App) Project Description: I need a developer to build a small web feature: Core Requirements Users can create a room and share a link Users join the room Each user connects their Spotify Premium account When the host plays/pauses/skips, all users’ playback stays in sync Simple room chat Basic “Tip” button (Stripe Checkout) Must work smoothly on mobile browsers (no native apps) Important You do NOT need to stream or host audio. Audio is played locally from each user’s Spotify account through the Spotify Web Playback SDK. Preferred Tech (flexible) React / Next.js / Node.js / TypeScript — or whatever stack you recommend. Deadline 14 days Budget** (fixed) ₹25,000 After awarding the project I will provide a more detailed breakdown and design flow. Deliverables: Create/join room pages Spotify login + player integration Synced playback Chat system Tip button via Stripe Checkout Clean, basic UI Working demo on Vercel or similar Source code + instructions Required Skills: React / Next.js Node.js / Express Real-time communication (WebSockets) OAuth integrations (Spotify is a plus) Stripe Checkout
