Bonjour ๐ I'm Ran Zheng
I design products for complex operational work. My work turning complex enterprise systems, data, and AI into experiences people can understand, trust, and act on.
Designing how complex supply chains make decisions.
At SAP, I design experiences for Integrated Business Planning, working with enterprise planners, product managers, engineers, and supply-chain experts to turn complex demand, inventory, supply, scenario, exception, and planning decisions into clear, actionable workflows.
Understand the operation
I study how planners investigate changes, move between aggregate and detailed data, trace business drivers, manage exceptions, and coordinate decisions across functions.
Design the decision
I design end-to-end workflows that help people understand what changed, identify why it changed, compare options, understand downstream impact, and decide what should happen next.
Build to think
I use Claude Code, and React to turn design concepts into functional front-end prototypes. Instead of stopping at static mockups, I prototype interaction logic, system states, edge cases, and realistic business data so Product and Engineering can evaluate the experience before implementation.
