Work Experience

Past & Current

  • Senior Product Designer, Design Systems | Thrive

    • Defining and building products that better the lives of the customers and drive business growth

  • Product Designer, Design Systems | Thrive

    I was responsible for maintaining and evolving our core design system to support consistent, accessible, and scalable product experiences. I partnered closely with engineering, product, and brand teams to build reusable components, document interaction patterns, and ensure alignment across platforms. My work helped reduce design and development time for new features by over 30%, while significantly improving UI consistency across the application.

    I also led accessibility improvements across the system, implementing WCAG-compliant components and conducting accessibility audits to close critical gaps—making the platform more inclusive for users with cognitive, visual, and motor impairments. Additionally, I collaborated with localization and content teams to scale our design system for multilingual support, helping us launch experiences in multiple languages and regions without sacrificing design integrity.

  • Senor UI | UX Designer | Wpromote

    I led the design of digital experiences for major global brands across industries like tech, consumer goods, and finance. My work consistently balanced strong visual execution with user-centered strategy. I collaborated closely with developers to ensure pixel-perfect implementation, reducing front-end QA revisions by over 40%.

    I helped shape UX strategy by conducting user interviews, stakeholder workshops, and competitive audits, which informed the direction of over 20 campaigns and microsites. These efforts directly contributed to improved engagement metrics—such as a 30% increase in conversion rates on a product landing page for a Fortune 500 client.

    I also created modular design systems that improved design efficiency across teams and cut production time by 25%. Whether building from scratch or elevating an existing brand, I delivered intuitive, conversion-optimized experiences grounded in both research and creative excellence.

  • UI | UX Product Designer | Tom Ferry

    I created intuitive, inclusive experiences that help users achieve real results. At a B2C real estate coaching SaaS company, I designed features that made agent training more effective and engaging—contributing to a 28% increase in course completion rates.

    I worked closely with Product, Engineering, and Client Success to turn user insights into thoughtful design solutions, while also leading accessibility improvements like enhanced contrast, keyboard navigation, and screen reader support.

  • From Web Designer to Product Manager to Developer

    In my previous roles, I wore many hats — designer, developer, strategist, and product thinker—which strengthened my ability to approach product design holistically. I designed and developed customer-centered websites and applications, created reusable templates and UI systems, and led usability testing and research initiatives to support user flows, site architecture, and product direction. My work directly improved performance, engagement, and scalability across multiple platforms, while also supporting the development team with optimized assets, design specs, and front-end structure.

About

Myself

I’m a senior product designer who specializes in design systems, scalable UX, and cross-functional collaboration. Over the last few years, I’ve led design system initiatives across startups and enterprise teams—helping product and engineering move faster with fewer trade-offs.

I’ve designed experiences that support mental health, improve financial literacy, and increase user engagement across mobile and web platforms. My work has driven measurable impact—like reducing tech/design debt by 30%, boosting adoption rates, and increasing retention through thoughtful UX.

What drives me most is building systems and tools that empower others—from reusable component libraries to accessibility standards that help teams scale inclusively. I also enjoy mentoring designers and fostering strong design-engineering rituals like office hours, QA workflows, and async critiques.

Currently, I’m looking for opportunities where I can own impactful product experiences, contribute to inclusive systems, and collaborate with teams who care deeply about both craft and outcomes.
