I'm Salvatore Filippone, a front-end web developer based in San Diego, where I translate designs into code.

I'm a seasoned web design and development professional with 28 years of experience delivering user-centered digital solutions across diverse industries. Based in San Diego, California, I specialize in HTML5, CSS3, JavaScript and React.js with a strong emphasis on modern, responsive, and accessible web standards. My expertise spans from creating scalable atomic design systems to leveraging cutting-edge design tokens and Figma variables to ensure consistency across platforms.

Throughout my career, I have demonstrated exceptional ability to bridge the gap between design and development, translating complex requirements into clean, maintainable code. My decade-long tenure at Thermo Fisher Scientific as Staff Software Engineer showcased my leadership in creating design systems used by 22 internal and external teams worldwide. I spearheaded the development of the Aurora Design System, the premier user interface design library for Thermo Fisher Scientific instruments, and successfully introduced design tokens that evolved into Figma Variables, enabling seamless light and dark theme implementations.

As a dedicated freelance developer since 2000, I have served notable clients including Stereo Unlimited, Ron Ellis Pickups, and Adams Avenue Bicycles, handling all aspects of website creation from UI/UX design to SEO optimization. My passion for clean code, accessibility, and staying current with evolving web technologies like React.js, combined with my experience as an educator at the Art Institute of California, reflects my commitment to advancing the field and mentoring the next generation of web professionals.
