I Built a Fully Automated LinkedIn Posting Pipeline (Node.js + BullMQ + MongoDB)

Most people think consistency on LinkedIn is about discipline. I treated it as a backend problem. So I built a system that: fetches content from multiple sources generates LinkedIn posts using AI schedules them across the week and publishes automatically No manual intervention. 🚀 High-Level Flow The system runs on 3 stages: Content Fetching (Sunday) Slot Allocation + AI Generation (Monday) Scheduled Publishing (Tue–Thu) 📅 1. Fetch Scheduler Every Sunday, a scheduler pulls content from multiple platforms: const sources = [ " devto " , " github " , " medium " , " npm " , " Hashnode " , " nodeweekly " , " reddit " ]; Each source is processed and stored in MongoDB. Fetch Logic const rawItems = await FetcherService . fetchFromSource ( source , keyword ); for ( const item of rawItems ) { await FetchedContent . updateOne ( { url : item . url }, { $set : { ... item , source , }, $setOnInsert : { expiresAt : new Date ( Date . now () + 7 * 24 * 60 * 60 * 1000 ), }, }, { upsert : true } ); } Why
