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.
