About Me

I am a frontend developer with a strong focus on clean interfaces, usability, and thoughtful design.

I enjoy building modern web applications that feel intuitive and visually calm. My work blends technical precision with design sensitivity, always aiming for clarity and simplicity.

Over time, I developed a strong interest in UI/UX design, design systems, and micro-interactions — details that elevate good products into great ones.

When I’m not coding, I experiment with illustration, avatars, and animation to sharpen my visual thinking and creativity.
