I came to product design from engineering, and I still like to understand how a system works before deciding how it should feel.

I’m at ease with technical constraints. AI is part of every stage of my work, from research synthesis and competitive analysis to prototyping and documentation, and nothing it produces goes out without my review.

  1. Designed spend controls and two onboarding and verification flows for the B2B portal, and led Wally, the company's first unified design system across web, iOS and Android, with a brand layer for white-label clients, built with an AI workflow.

  2. developer.dell.com (+11% unique users), an internal developer portal for 13.8K engineers where provisioning dropped from months to minutes, and a GenAI orchestrator that sets up infrastructure for new projects.

  3. Managed a 26-person UX team (3 promotions) and led UX across 7+ client projects, including Whirlpool brands, Nestlé and Kimberly-Clark.

  4. Whirlpool brands: Brastemp, Consul and KitchenAid.

  5. Products for Obvia, NOZ and Grupo Zelo. UX Bootcamp coordinator.
