As principal designer in McKinsey’s Consumer Practice, I led design for an AI-assisted pricing platform and financial reporting tools, working closely with data scientists and engineers.

My focus was rapid prototypes that clarified decision rules, instrumentation, and guardrails—so complex models became explainable, auditable controls fit for production.

Those prototypes became blueprints for several client implementations and shortened the path from concept to shipped workflows, contributing to a +1.5–4 percentage-point lift in return on sales across a ~$175B retail portfolio.
