Colliding media and design to tell original stories

Frontend Development

Being self-taught, I’ve benefited from an ecosystem in which formerly siloed disciplines have been democratized on the internet. Starting with video editing as a teenager, writing and staging plays during and after college, and teaching myself to design and code ahead of the SaaS boom in 2010, I’ve always followed my curiosity. My northstars were to achieve financial success as a creative professional, while gaining increasing recognition for what I have to say. As you can imagine, generative AI has already benefited me as much as anyone professionally.

In 2025, I joined an AI startup called Mutable.ai as Founding Designer. It was acquired by Google six months later. As a Senior Designer at Google, I have access to the latest models and tools. This inspires me create tools that facilitate new forms of communication and self-expression that I can then use in my own work. This feels like the somehow unexpected and yet logical culmination of a career built on hard work an intuition.

A new kind of documentary
12 minutes

Over a decade ago, I wanted to make an thesis-driven documentary about Tulip Mania because it captured something quintessential about American culture. As I dove into it, there were very good reasons for that. The Dutch were settling Manhattan at the exact same time and that same culture shaped the United States in ways that aren’t widely discussed. I also wanted to explore what it would mean to have a documentary that allowed the viewer to dive deeper in subjects that appealed to them through UX.
Due to my limitations as a frontend developer and other blockers that have now been removed by AI, I have finally made the film I wanted to make. It’s a short documentary told in the style of Dutch Masters, featuring drilldown experiences that allow the viewer to explore their curiosity in more detail.
