The project
YCheap is included as a personal price-monitoring project. Public sources available during this update did not confirm a reliable repository or product page, so the case study stays intentionally careful.
Technical angle
This kind of system connects price collection, temporal snapshots, drop detection, alerts and a dashboard.
What it proves
It shows data-product skill: automate monitoring, turn variations into signals and build a useful interface without overstating a non-public source.
