Over Sandor

I am a Front-End Developer with over four years of experience building scalable and user centered web applications. I focus on creating responsive, accessible, and high-performing interfaces using modern front-end technologies. I have solid experience with HTML, CSS, and JavaScript, and I regularly work with frameworks such as React, Angular, and Vue to deliver clean, maintainable code. I enjoy collaborating with designers and back-end developers, solving complex UI challenges, and continuously refining front-end workflows to improve both user experience and development efficiency.
