Project Breakdown
The Problem
Global users experienced buffering and high latency when accessing high-bitrate audio files.
The Solution
Implemented an edge-caching strategy using CloudFront and optimized adaptive bitrate streaming (HLS).
Technical Challenge
Architecting a DynamoDB schema to support complex access patterns (search, filter by genre) without secondary indexes exploding costs.
Business Impact
Achieved <1s time-to-first-byte globally. Scaled to 50k concurrent listeners during launch events.
Key Platform Features
System Architecture
Vue.js 3 with Composition API. Virtualized lists for rendering large playlists performantly.
Serverless Python functions (AWS Lambda) for scalable event-driven processing (transcoding, metadata extraction).
DynamoDB single-table design for millisecond-latency access patterns at any scale.
Fully serverless stack deployed via Serverless Framework. CloudFront for global content distribution.
