What I'm looking for

I'm looking to lead discovery-to-delivery work on complex AI-powered, fintech, regulated-platform, or enterprise SaaS products, translating user research and technical constraints into intuitive workflows.

At Omnicom, I design AI-powered enterprise SaaS experiences, including a contextual assistant, semantic search for the Elements Digital Asset Management platform, and an AI ticket-writing agent. I also deployed a design system MVP that reduced UI delivery time by 25–30% and redesigned onboarding to increase conversion by 18%.

Previously at Engine AI, I designed an alert configuration flow adopted by JP Morgan, cutting setup time from 15 minutes to five. I lead discovery through delivery, using research, design systems, and rapid prototypes to turn complex fintech and regulated-platform workflows into usable products.
