Book an intro call. canonical: https://www.radbar.studio/ --- # Interactive moments that feel, respond, reward. For digital products that should feel alive. ## 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**: Branded, memorable interactions at key product moments: onboarding, celebrations, rewards, reveals. - **Games**: Playable Rive mini-games and game UI, with state-machine logic and runtime-optimised animation. - **App companions**: Characters and companions that react to user input and app state. - **Delightful surprises**: Small interactive details and easter eggs people remember without knowing why. Selected clients: Bevel, mymind, LinkedIn, Nu, Immutable, CSGOROLL, Inflight. ## FAQ ### 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. ### 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. ## Work ### Signature moments - [Signature moment · Rive interaction 11](https://www.radbar.studio/assets/videos/globe.webm): Looping demo of an interactive Rive piece in the “Signature moments” category by Bartek Radziejewski.
