6 Reviews

Sajit is an outstanding ML/AI tutor. He’s flexible with his approach and always tailors lessons around how you learn best. What really sets him apart is how he breaks down complex topics into simple, understandable chunks without losing depth. He’s incredibly patient — never moves on until you’ve fully grasped the concept — and always explains with clarity and genuine enthusiasm. Sajit’s friendly, approachable style makes even tough ML subjects feel manageable and engaging. Learning with him doesn’t just build knowledge; it builds confidence.

I’ve been taking online classes with Sajit Sir for Machine Learning and Data Science concepts and I must say his teaching style stands out. He has a deep understanding of the subject and explains even complex concepts in a very clear and practical way. What I really appreciate is that his sessions are not like typical theory-heavy classes and he always connects every concept with real world examples and hands-on implementation. He ensures that every doubt is addressed thoroughly, often through practical demonstrations which makes learning both engaging and effective. Overall, his way of teaching has really strengthened my understanding and interest in the field.

When I first started learning AI/ML, I was a complete beginner and honestly, I lacked the confidence to even think of myself as a future data scientist. I was also weak in speaking and explaining concepts, simply because I didn’t have confidence in the subject itself. Everything felt overwhelming at the start, and I doubted if I could ever understand such complex topics.
But learning with Mr. Sajit has completely changed that. His teaching style is what gave me confidence he explains every concept so clearly and never minds if I ask the same question twice (or even more). He makes sure I understand it fully before moving forward. Because of this patience and clarity, I can now speak and explain concepts myself with confidence, something I never imagined when I began.
He connects lessons to real-world examples, going beyond toy datasets and instead using examples like highly imbalanced data, threshold tuning, and gain charts to expose us to the practical side of data science. He also introduced algorithms like DBSCAN, K-Nearest Neighbors (KNN), and various ensemble models, explaining not just how they work but also the differences, advantages, and appropriate use cases for each. His in-depth discussions on model evaluation, threshold values, and performance metrics helped me build a strong conceptual understanding. The way he demonstrated how unsupervised algorithms can support and enhance supervised models was particularly insightful. He explained concepts clearly and in depth, not merely introduced them.
This foundation has made me confident in tackling diverse ML problems and remembering complex topics in a simpler, structured way. With this learning, I was able to crack an internship position at Mercedes-Benz, which further improved my technical communication, problem-solving skills, and professional confidence.

Today, I can proudly say that I’m much more confident in my AI/ML journey, and I owe this transformation to Sajit Sir. If you’re a beginner like me, looking for a mentor who not only teaches but also helps you grow in confidence and real-world understanding, I highly recommend him.

I am in the 8th grade and I am incredibly grateful for the dedication and commitment Mr.Sajit, my AI teacher, has shown throughout my AI/ML journey.
When I first started learning, I had no knowledge of AI/ML, and I was a
complete beginner in this kind of coding. Despite these challenges, he
made the learning process of such a vast subject incredibly easy and
interesting.
One of my favorite parts about the way he teaches is his
ability to break down complex concepts and explain them in ways that
are easy to understand. For example, when teaching me about gradient
descent, he used a simple metaphor of moving around a mountain, which
helped me learn the concept very quickly.
His use of real-world examples and applications, like using AI to estimate the value of a car based on characteristics or to detect different types of cancers, helped me see how these concepts work in the real world, which has only increased my understanding.
Also, he always takes the time to ensure I fully grasp each topic, even if it means going beyond the usual class hours. Whenever I have doubts, he goes all out and above to ensure I don’t leave the class without my question being answered.
But the one thing I am extremely thankful for is how he teaches not
just the ‘how’ of a concept but also the ‘why’. Many teachers these
days just teach us the code needed to achieve a result, but they don’t
really explain why we do it that way. Mr. Sajit, on the other hand,
gives an explanation of each part of each line of code. Thanks to his
patient and effective teaching, I've learned so much more than I ever
thought possible in such a short time. I highly recommend him to
anyone looking to learn AI/ML in an interesting and solid way.

Sajit is an exceptional teacher with a deep understanding of LLMs. His ability to break down complex concepts into clear, digestible explanations made the learning process both engaging and effective. He was patient and thorough, ensuring I grasped each topic before moving forward. His dedication to teaching and his expertise in the subject truly set him apart. Highly recommended!

As this was my very first online one to one learning experience, I was quite skeptical when I initially reached out on TeacherOn and started receiving responses from tutors across India. However, from the moment I connected with Sajit Sir, I knew he was the one I needed to learn from. His empathy and genuine concern for me as a beginner in AI, combined with his deep passion, knowledge, and professional experience in the field, made all the difference.
Now, as I reach the end of this course, I can honestly say I’m blown away! 🤩 This journey has been more than just educational—it’s been transformative. From the first lesson, I felt an instant connection to the content and the way Sajit Sir delivered it. He has an incredible talent for breaking down complex topics into something approachable, and his passion for AI is truly inspiring. His patience in explaining topics, sometimes more than once 😊, was a huge help.
The balance between the course content and interactive elements made the learning process both enjoyable and impactful. Each new module was exciting, and the hands-on projects boosted my confidence, showing me that I was really grasping the material.
But more than the knowledge I’ve gained, this course has given me a renewed sense of direction in both my personal and professional life. 😎 If you're looking for a tutor that not only teaches you but also ignites 🔥 your passion, look no further. This experience has genuinely been life-changing!
