Kazunari Hara

Worked extensively on the openameba/spindle repository, delivering a wide range of features and improvements across UI components, design systems, and developer tooling. Focused on scalable front-end architecture, the work included building and refining component libraries, automating Figma-to-code workflows, and modernizing CI/CD pipelines using TypeScript, Node.js, and CSS. Enhanced accessibility and documentation, introduced robust testing with Vitest, and migrated the monorepo to PNPM for faster, more reliable builds. The approach emphasized maintainability and consistency, with regular updates to design tokens, integration of automated code quality tools, and streamlined onboarding processes, resulting in a more efficient and developer-friendly codebase.
