I’m putting together a web-based tool that lets auto dealerships pounce on newly posted vehicles the moment they appear online. The first module I need built is a real-time alert engine focused solely on “New listings alerts.” Here’s the core flow I have in mind: the service works with online marketplaces as well as selected private-seller websites, detects any fresh listing that matches my simple criteria (make, model, year, mileage or price range), and immediately pushes a notification—email, SMS, or webhook—to the dealership’s CRM. Speed is everything; a delay of even a few minutes wipes out the advantage. Open to discuss strategy and tech stack Acceptance criteria • A rules screen (or config file) where I can add or edit search criteria without touching code • Sub-60-second average latency from listing appearance to alert delivery, demonstrated in testing • JSON webhook payload + human-readable email format • Dockerised repo with README covering setup and environment variables We might later expand to price-drop or competitor-action alerts, so structuring the code for easy future add-ons will be a plus. If this sounds like a fun sprint, let’s talk timing and milestones.
