Tuomas Kivioja publishes the Internet Made Coder YouTube channel, focused on practical career advice for self-taught developers and on the algorithm / interview-prep material needed to break into well-paying engineering roles. The channel name reflects his own background as a developer who learned online rather than through a formal CS degree.
His CourseFlix listing carries Master Data Structure & Algorithms & Crack the Coding Interview — a paid Python-based DSA course aimed at developers preparing for technical interviews at large tech companies.
