Evgenii Ray is a software engineer and educator focused on the front-end engineering interview process — particularly the system-design interview rounds that gate senior front-end roles at large tech companies, plus the broader career-prep material.
His CourseFlix listing carries two Evgenii Ray courses: Fundamentals of Frontend System Design and Interviewing for Front-End Engineers, v2. Together the courses cover the technical and interview-process side of landing senior front-end roles.
Material is paid and aimed at front-end developers preparing for senior-level interviews. For broader content, see CourseFlix's Frontend System Design and Career & Interviews category pages.
