Summary
👤
Senior🎓
Top SchoolDan Greenheck is a versatile software engineer and entrepreneur with 10 years of experience building 3D web and embedded systems, now running two companies that deliver Three.js/WebGL consulting and training. He blends hands-on front-end 3D development with a strong background in navigation, sensor fusion, and embedded firmware from roles at Blue Origin and in aerospace research, enabling him to tackle both visual and computationally complex problems. Dan has produced commercial iOS apps and open-source tooling—his OpenFracture work demonstrates practical computational geometry skills applied to mesh slicing and game development. Based in Green Bay, he helps small businesses and developers augment e-commerce and web experiences with interactive 3D models while also teaching others to do the same.
