As technical lead of the design system at Clari, I built a self-sufficient codebase with automated testing, optimized builds, and versioned releases. I collaborated with the design team on system naming and design tokens, while advising on component semantics and accessibility. I maintained comprehensive documentation and served as the primary support contact, helping the system grow and educate users. Additionally, I standardized front-end tooling and architecture, evaluated technical candidates, and led regular practice group meetings to share knowledge.

• Wrote custom GitHub workflow action to send Slack notifications when new versions of libraries were released
• Created codemod scripts to automate updates after major version releases, reducing the effort for teams to upgrade
• Led adoption of Chromatic for visual regression testing of UI components
• Used Vitest/Jest, React Testing Library, and Storybook for testing UI
• Worked with CSS Modules and Sass for styling

At Showbie, I worked across three products, building features for the main app and helping integrate a newly acquired app, including TypeScript refactoring. I implemented design system foundations with cross-platform design tokens and Storybook documentation, later extending these patterns from React to Ember for a new Admin app. I championed front-end best practices, led Tailwind CSS adoption, advocated for accessibility improvements, and maintained the marketing websites.

• Rebuilt voice-note recorder UI from canvas to CSS, resulting in a more performant UI that was less obtrusive
• Provided static site generation solution for a rebranded marketing site that dramatically reduced monthly hosting costs

At Lift I developed diverse web projects ranging from small business sites to major marketing applications. I collaborated with Django developers on CMS configuration, worked with designers on responsive UI, and provided client CMS training. For WordPress projects, I handled hosting setup and backend configuration. I improved our front-end development process by implementing Sass architecture and Webpack bundling. I also helped develop a reusable component library to accelerate project development for both designers and developers.

• Built custom sites on Squarespace, Wagtail, and WordPress content management systems
• Explored dynamic visual treatments using GSAP animation, SVG filters, and modern CSS features
