Heleri Mandla contributed to the TEHIK-EE/tedi-design-system by building and refining React components focused on UI/UX clarity and flexible design patterns. Over three months, Heleri enhanced the vertical stepper with interactive step items and improved subitem rendering, enabling richer navigation workflows. She addressed usability by implementing visible active states for table filters and resolving placeholder visibility issues in multi-value select inputs, directly improving accessibility and user guidance. Her technical approach combined CSS, TypeScript, and Storybook to ensure maintainable, well-documented components. The work demonstrated thoughtful component design and a focus on cross-project consistency, supporting faster iteration and easier onboarding for teams.

September 2025: Delivered key vertical stepper enhancements in TEHIK-EE/tedi-design-system, improving interactivity and flexibility for navigation steps. Implemented an icons/links container within StepItem, added onClick support to StepItemProps, and refactored styling for the new composition with improved visuals and cursor cues. Expanded SubItem to render title, href, as, and onClick, enabling link and button rendering with richer interactivity. Removed description prop from StepItem to align with the additional-info component pattern, enabling more flexible content composition. These updates lay the groundwork for richer step-based workflows and consistent cross-project usage.
