Personal Note

I didn't get the chance to study in a Tier-1 school or college, but I'm extremely proud of where I am today. A big part of that growth comes from people like Prof. David Malan, whose teaching helped me fill the gaps I had always felt in my learning journey. I don't have a formal certificate from Harvard or CS50—but thanks to the internet and educators like Prof. Malan, I've learned concepts I missed during my student years. His teaching style is truly exceptional. He explains even the most complex topics in a way that anyone can understand within minutes. Knowing something is one thing. Teaching it so clearly that it transforms someone's life—that's a completely different skill. Prof. Malan is brilliant at both. I deeply appreciate what he has contributed to learners across the world, including me. I wish him great health, and someday, I hope to teach others the way he teaches—so I can uplift lives the same way he helped uplift mine.
