The challenge
Sustaining high throughput across personalized feeds, group content, and direct messaging while keeping commerce trustworthy and moderation actionable in the moment — without expensive unbounded joins on every read or a monolith that fights every new feature.
Our approach
We structured the backend as modular NestJS services with clear domain boundaries for social, groups, messaging, and commerce. Cursor-based pagination and Redis cache invalidation kept feed reads fast under concurrent load. Socket.IO with a Redis adapter handled horizontal WebSocket scale, and Bull queues kept post side-effects and notifications out of the request thread.
The result
A platform that handles real-time activity, RBAC with custom org roles, and Stripe commerce in a single system — with a clean split between synchronous work and background processing that holds up as volume and role complexity grow.
