takeUforward is the YouTube channel and paid-course brand of Raj Vikramaditya (Striver), an Indian software engineer (formerly at Google) and one of the largest independent algorithm / data-structure educators online. The channel's Striver A2Z DSA Course/Sheet is one of the most-used free DSA-prep references on the internet.
His CourseFlix listing carries three takeUforward courses: Computer Networks, DBMS (Database Management Systems), and Low Level Design. Together the courses cover the foundational CS topics that gate large tech-company interviews alongside the algorithm material the channel is best known for.
Material is paid and aimed at engineers preparing for technical interviews at large tech companies, particularly the Indian-tech and FAANG-tier interview circuit where the CS-fundamentals questions are common.
