For the next-generation rPDU (Rack Power Distribution Unit), I led the design initiative of the touchscreen HMI interface, transitioning the product from a legacy button-based navigation system to a modern, fully touch-enabled experience.

I evolved the corporate design system to support embedded hardware constraints, defining new interaction patterns tailored to a compact industrial touchscreen. Through user testing and close cross-functional collaboration with engineering and stakeholders, I iterated on workflows and screen architecture to improve usability, clarity, and efficiency in high-stakes data center environments.
