Product Collation
I created an object-oriented solution that also took advantage of some functional programming practices. It is a black-box service that takes an industry, all of it’s products, and a store as initial arguments. Filtering and sorting actions taken by the user trigger internal methods that act on the data and update the store.
Development of these features took a few weeks. We took the next few months to iron out bugs, uncommunicated or forgotten business logic, and other edge cases that we wanted to address.
