About me

Hi! I’m Javier García Domínguez, a front-end developer with experience building modern and interactive web applications. I focus on creating clean, fast, and visually engaging interfaces, working mainly with React, JavaScript, and TypeScript, and always paying close attention to user experience and performance.

I’m especially interested in interactive and immersive web experiences, including 3D graphics and animations with Three.js and WebGL. I enjoy exploring new technologies and experimenting with creative solutions that enhance how users interact with the web, while continuously improving my skills and the quality of the products I work on.
