The brief
A UK e-commerce operation needed continuous product-intelligence data pulled from Amazon and eBay at a concurrency level that trips most anti-bot systems within minutes of starting.
What we built
A NestJS/TypeScript backend with Redis and BullMQ handling distributed job queues, so scraping work runs in parallel and retries safely instead of depending on one fragile long-running script. TOTP multi-factor authentication is built in for account-level compliance, with an Angular dashboard giving real-time visibility into job status and results.
Where it led
The scraper is in active deployment for the client, and the same underlying infrastructure is what powers ASIN Grabber, the free tool in our Tools section — built from real production experience, not a demo.
