I combine clear pedagogy with interactive technology to break down the barriers to learning science — building tools and resources that make complex concepts intuitive, accessible, and free for everyone.
So many bright, curious students were hitting the same walls in physics. They weren't struggling because the concepts were too hard — but because of common, predictable misconceptions.
I realised my true calling wasn't just to teach, but to build a system that could proactively find and fix these hurdles at scale. What started as a few videos for my own students has grown into a mission-driven ecosystem of over 2,200 lessons and interactive tools — all dedicated to one goal: making a deep, intuitive understanding of science available to anyone, anywhere.

Clear, concise, exam-focused material for the IB Physics curriculum — designed to build student confidence and a clear pathway to academic success.
I design and code simulations from the ground up, turning abstract scientific principles into tangible, explorable digital experiences.
I lead projects that integrate physics with coding, AI, data analysis and mathematics — a holistic, modern approach to scientific inquiry.
Their curiosity and dedication are a constant source of inspiration. Here is what some of them shared about their journey.
Though I had a lot of difficulties with physics, he patiently helped me throughout my IBDP journey. His passion for physics makes his teaching interesting and easy to understand, even for difficult concepts.
Rajveer · 2023 BatchStudent at NMIMSHis teaching is highly practical, making complex concepts easy to understand. What stands out most is the special interest he takes in each student. His ability to connect theory with real-world applications made learning physics engaging and meaningful.
Vihaan · 2024 BatchStudent at University of CincinnatiDr. Rathankar played a pivotal role in my success in IB Physics. The depth of his knowledge lets him simplify the most complex topics. His constant support, insightful explanations and improvements in IA style boosted my performance.
Nayya Shah · 2023 BatchStudent at Parul UniversityWhile AI can provide facts instantly, can it truly teach? This question led to my latest project exploring the intersection of AI and education.
