About
Mathematician, educator & builder.
I teach mathematics, build software, and analyse data. I split my work between rigorous problem-solving and practical shipping — students get clarity, businesses get systems that work, and clients get clean, honest analysis.
My academic profile lives at rizwan.phd. This site is for everything else.
