What type of work do you usually do?
I design, animate and build expressive Rive interactions for apps and web — celebrations, rewards, characters, mini-games, interactive UI and signature flows that are meant to be remembered.
Interactive moments that feel · respond · reward. For products that show someone cared.
I'm Bart — a Rive creative technologist.
I design and build expressive interactions, from micro-moments and signature flows to product details people remember without knowing why.
- signature moments
- games
- app companions
- delightful surprises
Can you own the Rive side of a project?
Yes. I often work alongside animation teams, turning their work into a coherent, production-ready Rive experience — handling structure, logic, state machines, technical constraints, optimization and implementation.
Can you work with our existing design team?
Absolutely. I often plug into product or design teams as a Rive / interaction specialist — from early concepts to production-ready implementation.
