My largest engagement in this space was a $76K, 6-month character system for an educational app: two interactive avatars with 13 emotional states, skinning, customization, UI button components, a layered background system with galaxy and particle effects, and audio integration. 103 animations across 9 state machines and 3 ViewModels. I also built the "Willo" character for a developer education platform - responsive layout, parallax backgrounds, emotional state animations used in their game and on their website.
