Illustration · Misc.

I am primarily a designer, not an illustrator. I prefer to hire the illustrators. Sometimes, however, I get to stretch myself and do some illustration work for my clients.

Since I don’t regularly practice this side of my craft, I never really developed a singular style, like many illustrators do. Instead I’ve dabbled in many styles. Jack of all trades, master of none, I guess.

Here’s a sampling of various illustrations from over the years.

Fitbit · Fitness tech startup
We developed several different illustration styles for various Fitbit communications needs. We used a technical illustration style for some packaging and how-to guides, using simple line drawings that would scale well. As we added more product features to the devices and mobile apps, we needed to educate the users on how to use them, so I proposed a “Fitbit 101” online guide, using screenshots and drawings to illustrate it.

Fitbit · Fitness tech startup
At the same time Fitbit was adding more features to the devices, the company was beginning to ship products internationally, which meant we needed to develop cost-effective packaging. I created a text-less, illustrated startup guide to be inserted in the Zip product box, so we could use it in any boxes shipped around the world. The above photo is a press-check sheet, with multiple guides printed on one large sheet, which would later be cut horizontally and folded into a small booklet.

A series of educational photo-illustrations for International Dark Sky Week showing some of the causes and effects of light pollution.

“Bortle Scale” — The Bortle Scale (top image) is one of the ways by which light pollution is measured. Cities, towns, and suburbs cause the majority of light pollution, although rural places don’t get a pass — overlighting or poorly aimed lighting causes light pollution everywhere. This image was chosen by the Smithsonian Institution, Museum of Natural History, used in an exhibit called Lights Out, running in Washington DC from 2023 until December 2025.

“Shielded vs. Unshielded Lights”, “Light Pollution Harms Wildlife” — Our cities and towns are filled with light fixtures that spill light upward into the sky, where it’s not only useless to humans, but harmful to many species like bats, moths, owls, and more.
