Hi, I’m Long – an iOS Engineer in Irvine California with +7 years of corporate iOS Development experience

I just finished developing T-Marker. An app that turns the iPad into a surgical device used during full-arch dental surgery which leverages computer vision and augmented reality to obtain scan body pose estimation within 50 microns of accuracy. This allows permanent dentures to be installed directly into patients’ mouths with absolute fit and finish for maximum comfort and functionality.

My passion is and always has been working toward the democratization of goods and services and am always on the lookout for projects that would allow me to delivery ever greater positive impact.

T-Marker

  • Developed T-Marker, an iPad app that uses photogrammetry to achieve sub-50 micron accuracy, improving the fit and comfort of permanent dentures for patients during full-arch dental surgery.
  • Designed an OpenCV2-based AR interface to guide users through ArUco marker capture for precise alignment.
  • Built the app’s UI with SwiftUI, Objective-C, and C++, ensuring seamless integration with a desktop app suite.
  • Reduced 3D mesh size from ~50MB to under 64 bytes, cutting mobile-to-cloud upload times and storage costs.
