Rohan Kokane worked on the razorpay/blade repository, focusing on a comprehensive cleanup and upgrade of the Blade Design System. He removed outdated theme configurations and migrated both blade-core and blade-svelte components to Spark design tokens, ensuring consistent UI styling and improved maintainability. By achieving design and token parity with React components, Rohan addressed cross-platform consistency and updated related stories, linting, and changesets. His work, primarily using CSS, TypeScript, and Svelte, established a robust foundation for future theming enhancements. The depth of the changes supports faster iteration and positions the Blade system for scalable, maintainable front end development.
