get.interviewready.io is the paid course platform of Gaurav Sen, a software engineer (formerly at Uber) and one of the most widely watched system-design-interview educators on YouTube. His teaching style focuses on building the mental model from first principles — load balancers, sharding, queues, the trade-offs of CAP — rather than memorising specific architectures.
The CourseFlix listing carries his System Design Course and AI Engineering Course. Material is paid and aimed at engineers preparing for senior-level technical interviews at large tech companies, plus a newer track on building AI / LLM-powered systems.
