Where live commerce meets digital entertainment
Traditional e-commerce platforms lack the engagement and urgency that drive high-conversion events. Live shopping experiences were fragmented — streaming tools, auction engines, payment systems, and gamification existed in isolation with no unified commerce backbone.
The live commerce market reached $35B in 2024, driven by social commerce trends in Asia expanding globally. Existing solutions either excel at streaming (Twitch model) or commerce (Shopify model) but no platform delivered both in a cohesive, real-time, gamified experience.
Event-driven microservices architecture with domain-separated bounded contexts: Auction Engine, Wallet Service, Stream Manager, Notification Hub, and Analytics Pipeline
WebSocket infrastructure handling 50K concurrent connections with automatic reconnection, heartbeat monitoring, and graceful degradation to SSE fallback
Double-entry bookkeeping for the wallet and escrow system — every credit has a corresponding debit, enabling real-time balance reconciliation and audit trails
CDN-first media pipeline with adaptive bitrate streaming, thumbnail generation, and clip extraction for post-event commerce
Redis-backed auction state machine with optimistic concurrency control — bid validation in < 5ms with partition-tolerant write-ahead logging
CQRS pattern separating read and write models for auction data — writes go to PostgreSQL, reads served from Redis-cached projections
Redis Sorted Sets for leaderboard state, Lua scripts for atomic bid validation, and pub/sub for instant UI propagation. Every bid is idempotent with client-generated UUIDs preventing duplicate processing.
Stripe Connect with custom accounts. Funds held in escrow until delivery confirmation. Automated dispute resolution flow with 72-hour arbitration windows. Double-entry ledger ensures every transaction is auditable.
RTMP ingest → HLS transcoding pipeline with 3 quality tiers. Latency optimized to < 3s using LL-HLS. DVR capability for replay and clip generation.
Horizontal pod autoscaling based on WebSocket connection count and bid queue depth. Auction state partitioned by event ID, allowing independent scaling per live session. Read replicas serve dashboard analytics without impacting auction write performance. CloudFront edge caching for stream assets reduces origin load by 94%.
Three-layer revenue model: (1) Platform commission on every transaction (5-12% tiered by seller volume), (2) Premium seller tiers with enhanced analytics, priority placement, and lower commission rates, (3) Gamification credit system — users purchase credits for bid boosts, virtual gifts, and exclusive event access.
