Product designer. UX strategist. Design leader.
I’m Mary Ann Saulong Lewis, a New York-based product designer and UX leader creating clear, scalable experiences across mobile, web, tablet, and television platforms.
I bring together UX strategy, UI craft, research, design systems, and leadership to turn complex product challenges into experiences that feel simple, useful, and human.
What I do best
UX Strategy
I translate ambiguous product problems, user needs, and business goals into clear experience direction, journey flows, and measurable product opportunities.
UI & Interaction Design
I design polished, intuitive interfaces with strong visual hierarchy, thoughtful interaction patterns, and platform-aware details across web, mobile, and TV.
Design Systems
I create scalable components, patterns, and standards that improve consistency, accessibility, and team velocity.
Research-Informed Design
I use qualitative and quantitative insights to reduce guesswork, validate decisions, and shape experiences around real user behavior.
Design Leadership
I mentor designers, guide critique, align cross-functional teams, and build frameworks that help design teams grow with clarity and confidence.
Where I’ve made impact
AI & 0→1 Product Innovation
Shaped early product vision and hands-on UX/UI for AI-assisted research experiences.
Streaming & Cross-Platform Experiences
Designed products across Apple TV, Roku, AndroidTV, Xbox, PlayStation, web, and mobile.
Consumer & Enterprise Products
Led work across entertainment, telecommunications, market research, survey platforms, operational tools, and design systems.
Scalable Product Foundations
Turned fragmented UI patterns and complex workflows into reusable systems, clearer standards, and more reliable product experiences.
How I work
I’m at my best when the problem is complex, the path is unclear, and the team needs both strategic direction and hands-on execution.
I like to zoom out to understand the system, then zoom in to refine the interaction details, visual craft, content, and user moments that make the experience work.
My approach is grounded in a simple belief:
Great design makes complexity feel clear, useful, and human.
