I have had an incredible experience with Mehul on Topmate. His dedication to sharing valuable resources for Data Structures and Algorithms (DSA) and system design has been immensely helpful. The DSA sheet he provided is comprehensive and well-structured, making it easier to grasp complex concepts. Mehul’s curated resources, such as the System Design Roadmap, Frontend System Design, and various backend system design guides and insightful YouTube videos are invaluable. Moreover, Mehul is patient, knowledgeable, and always willing to go the extra mile to help you.
