Carlos Bertomeu developed and expanded the Factorial One design system in the factorialco/factorial-one repository, focusing on scalable UI components and cross-platform consistency. He implemented features such as embedded navigation, a React Native component library, and a unified styling approach using TypeScript, React Native, and Tailwind CSS. Carlos introduced a modular icon system, enhanced Storybook integration for multi-theme testing, and delivered new modules like Inbox with filtering and reusable headers. His work included dependency management, CI/CD configuration, and codebase cleanup, resulting in improved maintainability, developer velocity, and a robust foundation for future UI/UX enhancements across web and mobile platforms.

June 2025: Delivered a refreshed Inbox experience in factorial-one, featuring a List View with sections and an extensible PageHeader, introduced filtering to improve message management, and performed targeted cleanup to reduce dead code. The changes enhance user productivity, maintainability, and code quality while aligning with business goals of faster, more intuitive inbox workflows.
