I am an experienced software and hardware developer who designs new ways for humans and computers to interact. I focus on visual languages and spatial interactions, which means I develop cutting-edge software and hardware interfaces that move beyond the screen.

I also do interactive 3D form generation and visualization of large and complicated data sets and models.
