Isaac Rios

I’m a Frontend Engineer with over 4 years of experience building accessible, performant, and scalable React interfaces. My work bridges design and development through component-driven architecture, design systems, and scalable CSS/SCSS solutions. I focus on crafting polished, responsive interfaces that balance usability, maintainability, and technical performance.

At ElementaryML, I architected modular CSS/SCSS systems, developed reusable React components, and implemented a dynamic theming solution supporting multiple client brands. I also have hands-on experience building HTML/CSS email templates, which gave me practical exposure to cross-client rendering challenges and strengthened my precision in layout consistency and QA testing. While not my primary focus, I’m open to deepening my skills in email development and leveraging my frontend foundation to contribute effectively in this area.

Recently, I’ve been advancing my JavaScript and TypeScript expertise through personal projects focused on state management, functional programming, and reactive UI design. These projects have strengthened my understanding of both object-oriented and functional paradigms, while refining my problem-solving and architectural thinking.

I’m particularly drawn to roles that connect design and frontend engineering — where attention to detail, strong CSS architecture, and creative problem-solving come together to deliver seamless user experiences.
