CAD SYSTEMS · COMPUTATIONAL GEOMETRY · APPLIED MATHEMATICS
I design computational systems that turn geometry into industrial decisions.
I’m Hananiah Hsu, a C++ and CAD software engineer working across parametric modeling, B-Rep geometry, engineering algorithms, and the mathematical structures beneath reliable industrial software.
SELECTED WORK
