Frontend

Welcome to my personal website! My name is Konstantin Dzuin, and I am a Lead Frontend Engineer with over 20 years of experience in UI development, design systems, and team leadership. I specialize in React and TypeScript, building scalable design systems and focusing on both user experience (UX) and developer experience (DX).

My expertise spans from creating visually appealing and user-friendly interfaces to leading high-performing frontend teams. I specialize in building complex data interfaces, administrative dashboards, and internal tools that handle large datasets and intricate user workflows. I've worked on high-impact projects like Quack, Stereo, Badoo, and Bumble, while driving adoption of best practices in accessibility, performance, and maintainability. Beginning in the late 1990s, I've navigated the evolution of frontend technologies while maintaining core development principles, allowing me to deliver solutions that are both innovative and reliable.

I am currently open to new opportunities in frontend UI engineering and team leadership. If you're looking for an experienced Lead Frontend Engineer with a strong focus on UI design, team management, and scalable architecture, connect with me on LinkedIn.

Through this website, I hope to share my work and experiences with you. Please take a look around and feel free to get in touch if you have any questions or would like to work with me. I am always open to new challenges and opportunities to improve my skills and deliver the best results to clients.

Note: You may also find my work under “Konstantin Dziuin” in some places. Both spellings refer to me — my legal name is Konstantin Dziuin, though I've used Dzuin professionally in some contexts.

Photography

In my free time, I indulge in my passion for photography, capturing the beauty of the world around me through my lens. I am a versatile photographer, who enjoy capturing memories for families, friends and kids, as well as the beauty of the night sky through astrophotography. I enjoy the process of capturing stunning images of celestial objects, such as stars, galaxies, nebulae, and other deep-sky objects as well as capturing candid and natural images of people.
