I'm a mathematics masters Student teaching mathematics Online and in person in Leiden.

Having known Rishabh for years, I’ve witnessed his growth into an outstanding educator who brings not only expertise but also a genuinely fresh perspective to teaching mathematics. His approach is deeply centered on fostering meaningful understanding, but what truly sets him apart is his unconventional way of thinking. Rishabh has an incredible ability to approach problems from unique angles, encouraging his students to break away from standard methods and think critically about new solutions. Rishabh's teaching style is as engaging as it is enlightening. He challenges students to consider multiple perspectives, often reframing a problem in ways that make them rethink their initial assumptions. This approach not only clarifies complex ideas but also ignites curiosity, inviting students to explore the “why” behind every concept. His ability to simplify challenging topics, while also presenting them from a fresh viewpoint, instills confidence in students and allows them to connect with the material on a deeper level.
For students who want to dive into mathematics from multiple angles and explore ideas beyond conventional boundaries, Rishabh is an exceptional guide.

I have known Rishabh since my school days, and having shared a lot of study sessions and discussions with him, I am inspired by how he approaches a subject to the point that it is not an exaggeration to say that I owe him my own study methodology.
He knows the role of intuition in problem-solving and believes in a thorough understanding of a topic rather than surface-level knowledge to pass exams. This relentless pursuit of in-depth knowledge is only possible because he genuinely loves mathematics to the core, and you can really see how much he enjoys it whenever you brainstorm with him!
Time and again, in both high school and college, I have always loved understanding anything I find challenging from Rishabh because he assumes no prior knowledge and emphasises building intuition and visualisation. I highly recommend Rishabh to students who learn by exchanging ideas, building intuition, and spending hours engrossed in racking their brains on that *one thing* they don't have a feel of yet.

P.S. Do occasionally catch him over coffee to discuss life (beyond academics), and I am sure you'll take home some fresh perspectives and interesting takes to take home : )

In the 10 years that I have known Rishabh, I have seen his love for math blossom from a mere curiosity to a passion for life. Not only is he humble and devoted, but also excels in learning and understanding new concepts intuitively and quickly. In our time at high school and college, he has mastered several subjects and collected many merits and accolades. I often sought help from Rishabh whenever I wanted to understand difficult topics, especially in number theory. His explanations are easy to understand and he accommodates his lessons according to the level of understanding of the learner. With a focus on building intuition, he has always emphasized deep understanding rather than rote learning even if that sometimes means taking the long way. Most importantly, I could always feel his love for the subject which I believe to be the most important trait that makes studying enjoyable.

I highly recommend Rishabh to learners who prioritize understanding, excellence and passion for the subject.
