Product designer. UX strategist. Design leader.
I’m Mary Ann Saulong Lewis, a New York-based product designer and design leader with 15+ years of experience creating intuitive experiences across mobile, web, tablet, and TV/OTT platforms.
I turn complex product challenges into shippable direction, combining UX strategy, UI craft, research and data-informed decision-making, design systems, and cross-functional leadership.
My work spans consumer, enterprise, and AI-powered products, including 0→1 innovation, streaming experiences, market research platforms, operational tools, and product system foundations.
What I do best
UX Strategy
I translate ambiguous product problems, user needs, and business goals into experience direction, journey flows, product frameworks, and measurable 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/OTT experiences.
Design Systems
I create components, patterns, and standards that improve consistency, accessibility, product quality, and team velocity.
Research & Data-Informed Design
I combine qualitative insights, usability testing, analytics, and product performance signals to identify friction, validate decisions, and connect design improvements to measurable outcomes.
Design Leadership
I mentor designers, guide critique, align stakeholders, and build frameworks that help teams make decisions with more confidence.
Where I’ve made impact
AI & 0→1 Product Innovation
Shaped 0→1 AI-assisted research experiences, including signal feeds, summaries, study generation, and executive-ready insight storytelling, with concepts projected to reduce time-to-insight by approximately 60%.
Streaming & Cross-Platform Experiences
Designed OTT/CTV experiences across Apple TV, Roku, Android TV, Xbox, PlayStation, web, and mobile, supporting cross-platform streaming growth and 300K+ MoM registrations.
Consumer & Enterprise Products
Led work across entertainment, telecommunications, market research, survey Improved consumer and enterprise product experiences across entertainment, telecommunications, market research, survey platforms, and operational tools, including a survey redesign that increased first-time user conversion by 30%.
Product Systems & Foundations
Turned fragmented UI patterns and workflows into reusable standards, helping scale design system adoption from under 30% to approximately 90% across new projects.
How I work
I’m at my best when the problem is messy, 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.
