## Projects

### HyperBIM

HyperBIM is a 3D builder for HyperFrame framing solutions. Designing a 3D tool on a 2D canvas brought a lot of interesting challenges, both from a UX and UI perspective, but also from an execution perspective. From finding the best way to combine 2D objects with a 3D model, to figuring out interactions in a 3D environment. All in all, exactly the type of project I love.

### Radiant

Way before AI was as capable as it is today, I had the opportunity to help create an AI-driven internal tool for email marketing at Canyon. Combining a canvas tool with AI, figuring out the best way to interact with it, and exploring what felt natural all felt like such a novelty at the time.

### WATS

A project that never came to fruition, but is still very dear to me. WATS is a waste management system designed to help large corporations reduce waste. It started with me helping out on UX and ended with creating a whole new design system. Even after the funding and project were halted, I continued exploring it because I had so much fun working on it.
