I'm Iskandar, a software engineering apprentice who enjoys doing mathematics in my free time. I built Riemannoid.io to connect people who love math and want to share, discuss, and solve interesting problems together.

Why is it called Riemannoid?

Riemannoid is named after the great mathematician Bernhard Riemann, who made major contributions to mathematics, especially calculus and mathematical analysis.

I find the idea behind Riemann sums fascinating, so the name Riemannoid is a playful way of describing someone who enjoys mathematics and solving problems - a Riemann-like math enthusiast.

Whether you are a student, a professional, or simply curious about mathematics, you are welcome to become a Riemannoid and join the community.
