Heleri Mandla developed the VerticalStepper component for the TEHIK-EE/tedi-design-system repository, focusing on hierarchical step navigation with enhanced accessibility. She implemented distinct step and sub-item elements, supporting multiple states such as completed, error, and disabled, and added optional icon support for compact views. Using React and TypeScript, Heleri refactored the component to export StepItem and SubItem, improved semantic structure, and wrapped the component in a nav element to meet accessibility standards. She also updated documentation to clarify desktop-only support for the initial release. The work demonstrated thoughtful component design and incremental improvements through a series of targeted commits.
