I usually maintain and design digital assets in Illustrator. I’ll design icons and other UI elements in vector and export to either Adobe XD or Proto.io to prototype and compose screens.
I’ve been using AdobeXD to design screens and configure basic user flow and interaction. For more complex interactions I will use Proto.io.
I use After Effects to create animations for both prototyping and branding.
I do 3D modeling in Maya and rendering for both product mockups and game assets. I really love using the Arnold renderer for product mockups.
Deskfruit is built using the Unity Game Engine. The AR functionality is made possible by Vuforia and I write C# scripts for the games, like this basketball shooter.
