SummaryProject Overview

We are upgrading a live Production & Inventory Management System for a Japanese manufacturer. In this phase, the main goal is to migrate existing Windows desktop screens to C# / WPF (MVVM) and implement unit tests for each screen. Detailed specifications and the legacy application are already available. You will join a Japan-Philippines agile team and work from our BGC (Bonifacio Global City) engineering hub.
