Hi, I’m Addie! I’m an enterprise product designer focused on complex, high-stakes systems, where scale and real business outcomes matter.

I’m a Senior Product Designer at CarMax, where I design experiences that simplify complex transactions and make selling a car feel effortless. My approach blends creative problem-solving with a technical understanding of how products are built: a perspective shaped by my early career in QA and engineering collaboration.

I design customer and associate facing platforms used by millions, turning messy requirements, legacy systems, and cross-functional tension into clear, testable experiences that ship.

From discovery to delivery, my work spans B2C and internal tools across regulated, multi-team environments.

I specialize in:

  • Complex flow design: multi-step, multi-input journeys (identity, documents, eligibility, scheduling, handoffs)

  • Cross-channel experiences: web, mobile, in-store, and internal tools that must work together

  • Enterprise discovery: store visits, stakeholder interviews, service blueprints, opportunity mapping

  • Designing with constraints: legacy tech, compliance, scale, performance, and edge cases

  • AI-assisted UX: quality checks, validation, automation, and human-in-the-loop workflows

  • Shipping & adoption: partnering with product + engineering through build, test, and rollout

See my work!
