I’m excited to share a backend system I built recently, designed to migrate thousands of images from various third-party platforms into a client’s product using a highly distributed and scalable architecture.
What I Built:
• Scalable backend pipeline for scraping, syncing, downloading & uploading
• Distributed architecture across AWS (ECS, SQS, Lambda) + client-side virtual machines
• 30+ parallel Node.js workers across 3 virtual machines
• Centralized observability via Datadog for real-time log tracking
The system reduced processing time from days to hours, handled large datasets efficiently, and was designed to recover from failures without restarting.
