Additional work

A closer look at vehicle comparison under real platform constraints.

This project shows a durable part of my practice: comparing interaction models, working within an existing component system, and separating observed traffic from claims the data cannot support.

Vehicle Comparison Service

I explored several ways to compare models and engines within Adobe Experience Manager constraints. The final direction kept vehicle selection and comparison results on one page, then used a popup for engine selection so users did not lose their place.

Service design, human-centered AI, and workflow transformation

I help teams make complex workflows clearer, more reviewable, and easier to act on.
