PROFILE
Johan Lundgren
Johan Lundgren contributed extensively to the scania-digital-design-system/tegel repository, focusing on accessibility, UI consistency, and modernizing frontend workflows. Over 14 months, he delivered features and fixes across components such as modals, dropdowns, and checkboxes, implementing ARIA attributes, color contrast improvements, and automated accessibility testing. Johan refactored the color system and migrated build pipelines to align with modern Node.js, while removing Angular dependencies to streamline releases. He enhanced developer experience by upgrading Storybook, refining SCSS variables, and enforcing TypeScript strictness. Using TypeScript, SCSS, and Playwright, Johan’s work improved accessibility compliance, maintainability, and cross-theme visual consistency throughout the design system.
