I am a SDE-3 at Flipkart, India's e-commerce giant, competing Amazon, leading a team to manage the B2B supply chain business. Previously, I worked at leading FAANG companies such as Amazon. I possess strong problem-solving skills, as well as expertise in low-level design (LLD) and high-level design (HLD). I can guide you in becoming a proficient software engineer or achieving promotions if you are already on this path.

💡 Teaching is my passion, and I love to mentor and upskill students. I am an ideal mentor for learning data structures and algorithms, system design, programming languages (C++, Java, Python), and other computer science subjects. With my extensive experience, you will undoubtedly benefit whether you aim to secure a position at a product-based company or achieve high marks in your computer science courses.

Feel free to reach out for mentorship if you are looking to upskill as a software developer. If your goal is to crack product-based company interviews, my personal guidance will provide you with the necessary preparation. Having conducted over 200 interviews myself, I have a thorough understanding of the interview process.

Additionally, I am passionate about competitive programming and have a strong coding profile, which I am eager to help you develop. I am always happy to discuss problem-solving and system design.

Throughout my career, I have felt the absence of a good mentor or teacher in my life, and I am committed to filling that gap for you. So, let's connect. I look forward to talking with you and assisting you in any way possible within the computer science domain.

Smart tutor.

Radib has been one of the best tutors in my career. He guided me through Java, Spring, Spring Boot, and essential AWS tools, all tailored to market needs. He also helped me with system design and version control, which enabled me to land a software engineering role in a top banking firm. I am still continuing with him to improve my skills.

Great Mentor!!!

In my experience with Radib Sir, I found him very knowledgeable, hands-on and having passion for teaching. He is systematic, and methodical in his teaching approach in Java and related technologies.
He explained the concepts with some real examples. He motivated me to write the code with best practices, and debug it independently, to build confidence in me. He is a thorough professional, who planned the schedule and lessons according to my need. I thoroughly enjoyed learning from Radib Sir, and come a long way in Java and related technologies. Thank you Radib Sir for all your help. Truly appreciate it!!!
