The Challenge
Publishing content across social media APIs is fragile. Each network has different size limits, image aspect ratio constraints, rate limits, and authentication formats. If an API is temporarily offline, it can stall the publishing queue, leading to missing or out-of-order content delivery.
The Solution
We built a centralized publishing scheduler. Designers compose and schedule posts in a unified interface. The system optimizes and transcodes media for each network, queues the jobs, and publishes them in parallel using independent worker loops with exponential backoff handlers.
System Architecture
The publishing manager is built using NestJS and a Next.js dashboard. Job state is held in Redis, with BullMQ directing execution schedules. An abstraction layer isolates social API integrations, protecting the core database from external schema changes and letting us add platforms dynamically.
