As seen on
Most of my career has been in marketing and advertising building immersive brand experiences, interactive campaigns, games - that kind of thing. That’s where I learned to prototype and build fast, which led to some work I’m proud of, including an FWA Site of the Year award.
I’ve spent just as much time on the product side too, building platforms and tools that need to hold up long-term. I really really enjoy going deep into the many disciplines involved like clean architecture, solid performance and code that doesn’t turn into a mess as the team grows. As a lead developer I’ve mentored engineers, set up CI/CD pipelines, and pushed hard on testing, accessibility and code quality.
Having done both is probably the most useful thing about my background. I tend to end up bridging creative ideas and practical implementation — which over the years has taken me through projects with Nike, Google, Spotify, MSCHF, Ghibli, and many others.
