Bidwatch - Search Live Ebay Auctions Ending Soon

This is a submission for Weekend Challenge: Passion Edition.

What I Built

I use ebay.com a lot as a passionate card collector to find auctions. It's super difficult to use their filters on both the web and mobile, but mobile is especially frustrating.

The goal was to build a simple app that allows users to search for any auctions on eBay, filter those listings, find the ones ending soon, and save their filter preferences to find auctions more quickly.

In Bidwatch, you can look for auctions ending soon with bids, no bids, or all auctions. These filters help you understand market sentiment for prices and see what's actually popular.

I've used the app many times now to win some really awesome auctions that I would have never seen otherwise.

Demo

How I Built It

AI helped me ship this pretty fast... I validated the idea was possible by starting up Codex Chat and explaining the basic MVP. It helped me research the ebay.com REST API offerings and confirmed it was possible to get all the data I needed.

Codex helped me create a PRD (Product Requirements Document) for the MVP. Initially, that was literally just pulling search data back. The scope grew over time, and more and more features were added, such as:

• Filters
• Authentication
• Caching
• Favoriting

Here is a quick look at the system architecture.

Excited to be part of this challenge and see all the other projects submitted. If you have any feedback or questions leave a comment.
