By training I'm a complex differential geometer.
In later years I've written introductory textbooks for real analysis, linear algebra, and group theory, text-based software for creating mathematically accurate diagrams in LaTeX and a miscellany of interactive web-based programs for teaching concepts from algebra, geometry, and (pre-)calculus. I've also helped digitize public-domain math, physics, and astronomy books for Project Gutenberg.
I am never deliberately condescending or insulting.
"Hwang" rhymes with "song".
