Evgenii Ray

Staff UI Engineer

Hi, my name is Evgenii, and I currently work as a Staff UI Engineer. My journey in tech started in backend engineering, where I soon discovered a passion for the dynamic and fast-paced world of JavaScript & UI engineering. I had a chance to work at JetBrains, which allowed me to contribute significantly to developing exceptional tooling for software engineers and crafting complex UI applications focusing on user experience and performance. I strongly believe in the power of knowledge being accessible to all. This led me to start my own YouTube channel in my spare time. I share content on Frontend Engineering, particularly in designing complex systems and web performance.

What They're Saying

I discovered Evgenii Ray's YouTube and Telegram channels by accident, and within a short time I'd watched every video and read every article. His explanations were so clear and practical that I enrolled in his 'Front-End System Design' course on Frontend Masters, and I'm really glad I did. Evgenii has a unique talent for explaining complex topics in a simple, structured way. All the nuances and difficult parts of front-end system design are covered through excellent examples that make the concepts easy to apply. I can't wait to see an extended or advanced version. Highly recommended!

This course takes stuff you kind of already know and actually nails it down. Nothing gets glossed over, every idea gets built up the right way instead of half-explained. Thanks for putting together something this solid.
