A comprehensive end-to-end case study on redesigning Blue Yonder's Microspace Planning application — transforming a legacy, ribbon-heavy desktop tool into a modern, collaborative spatial canvas. This project covers the full UX lifecycle: from legacy audits and user research to information architecture, low-fi wireframing, high-fidelity design, design system contribution, and rigorous dev handoff. The result: 50x faster workflows, 300+ screens delivered, and live validation at ICON 2025.
