Project History

  • My Gartner Mobile app
    Led product design, development, and launch of Gartner's client app, boosting key engagement, and retention metrics.

    Working with a cross-functional team, using in-house and agency resources, we replaced an outdated iPad app with an engaging, cross-platform app experience. The app was piloted on iOS to a small client cohort, then rolled out to all subscribers, with an Android version built as the app's numbers stayed strong.

  • PR Newswire Public Site
    Led the research, strategy, and design of a website relaunch, preserving PageRank performance while tripling inbound leads.

    My team was tasked with redesigning prnewswire.com to modernize its look and optimize performance. We had to maintain technical features that kept search performance strong. A corollary goal of the redesign was to improve the inbound lead generation funnel.

    The relaunched site was mobile-friendly and responsive, including all the necessary features, and integrating a rethought signup form for prospects that greatly simplified the process. This new site and form led to a 200% increase in qualified leads coming into our tracking system for conversion.

  • Clarins DTC eCommerce Site
    Launched a global beauty company's first website that sold direct to consumer, with sales that outperformed estimates.

    I came to Clarins to an outdated, marketing-copy-only website. The company had been selling online, through retailers and in a partnership concept called Gloss, but had not attempted its own eCommerce site.

    Working in partnership with colleagues in Paris, I led the design and development of Clarins' global direct to consumer launch. We created everything from translation tables for a consolidated build to the packing slip placed in orders on the pick line. Taking a holistic, end-to-end approach allowed us to focus on the details necessary to get the launch right.

    The site went live to users in the United States and France, then began rolling out to other countries, who had the option of enabling or disabling eCommerce. Domestically, sales greatly outpaced our initial estimates, and combined with partner websites, they vastly increased online sales' impact on company sales overall.
