I designed and developed the Android workflow around the moments where inventory work is most likely to slow down: identifying an item, checking its state, and updating it without losing the record behind the action.

Make the record usable at the point of work.

The implementation connects sign-in, barcode scanning, inventory CRUD, and Firestore-backed state. The product decision was to keep the useful action close to the item record rather than turn routine stock work into a long administrative flow.
