Professional Experience
Software Engineer @ Cinder2023 - Present
Cinder is dedicated to making the internet safer through advanced Trust and Safety software.
As the sole frontend engineer, I spearheaded the complete redesign of Cinder’s frontend, aligning it with future-ready architectural patterns and improving scalability for evolving Trust and Safety challenges. By implementing Bolt, our new design system, I streamlined our component library and introduced robust design tokens for consistent theming. This overhaul has simplified the development process, minimized potential errors, and enabled faster feature rollouts, empowering our team to build solutions that keep pace with the shifting digital landscape.
