  • Swirl Holiday Card (Development)

    The team decided that we would create a 3D interactive experience with Three.js as a base. Each year, we would create a holiday card that we'd send out to clients and then allow them to pick a charity that we would then donate to on their behalf.

    We utilized Preact as a base but the main 3D component was built using Three.js. The 3D assets were built in VR using an HTC Vive and Google blocks which were then imported into Three.js.

  • Viveport MailChimp Email Template (Development)

    Working with HTC to improve their newsletter process, I developed this dynamic MailChimp template system. Utilizing the Foundation 2 for Emails framework allowed me to build a rather complex and completely customizable template that enabled the output of any of the various types of weekly newsletters that they had been doing.

  • Sovos Brands Website (Development)

    We built a responsive WordPress-based site using the Visual Composer plugin to create an easy-to-edit and good-looking web experience. Utilizing the Visual Composer plugin allowed us to quickly build a robust and usable site.
