3D Render Workflow Manager

https://cora.creativedrive.com/
Led the creation of the desktop app that integrates with Autodesk 3ds Max to deliver all assets that a designer creates to our 3D workflow process. As the technical leader of the team, I organized demands and tasks and developed the application that controls the entire 3D rendering workflow. This included managing demands, distributing demands on our rendering systems, and managing the assets generated by the processes. The automated render process reduced the time to deliver a 3D model, guaranteed standardization in delivery, and increased the flow of 3D-rendered models.
