🚀 Architecture & Technical Achievements
Adaptive HLS Audio Pipeline
Engineered an asynchronous, highly scalable transcoding pipeline. When an artist uploads a track, a Celery worker downloads it from Cloudflare R2, uses FFmpeg to transcode it into multiple bitrates (64kbps, 128kbps, 320kbps, 1411kbps Lossless), and re-uploads the .m3u8 and .ts segments back to R2 for optimized CDN delivery. Playback on the frontend is seamlessly handled by HLS.js.
Zero-Trust Universal Hosting
Implemented Cloudflare Tunnel to securely expose the local Django server and Daphne WebSocket server to the internet. This creates a Zero-Trust environment without opening firewall ports or requiring a static IP, allowing the platform to be hosted anywhere.
Premium Subscription System
Integrated Razorpay to handle premium subscriptions. The system supports multiple flexible plans (weekly, monthly, annual) and manages transaction histories, granting users access to premium features like lossless audio and the professional equalizer.
