Quadruped

We create
apps and websites with legs.

A small agency with a big reach

We’re dedicated to doing great work for people who care about what they do.

Based in Portland, Oregon, we partner with entrepreneurs, businesses and nonprofits. Working with integrity and mutual respect, Quadruped builds interactive technologies that have a positive impact, provide value, and leave the world better than we found it. We build sites from the bottom up—from concept and content through technical development and design.

Shannon J. Wilson

Co-founder | Project Manager & Information Architect

A native Oregonian, Shannon has enjoyed 14 years of freelance and agency experience leading teams through large-scale projects for HP, NOAA, and SolarWorld. As a co-founder of Quadruped she devotes her friendly disposition, facility for detail and big ideas to every project.

Evan Heidtmann

Co-founder | Lead Developer

Evan has been making web apps for over a decade, and he loves it. With a background in large-scale visualizations, he brings a passion for analytical precision to his roles as an owner, developer, and systems administrator. Evan advocates for rock-solid infrastructure, modular and testable architecture, and client involvement at every phase of every project. When he's not building the guts of our applications, you can find Evan building rock walls in Forest Park or playing bluegrass banjo in a bar somewhere.

Jesse Firestone

Co-founder | Lead Developer

Jesse has been developing sites for nine years, contributing problem solving, integrity and a sense of humor to every project he’s touched. He helps our clients find the right technical solutions and builds sites with grace and style. An avid rock climber, Jesse brings the same strength, wit and dedication to his role as co-founder and developer as he does to his passions in the outdoors.

Agency Partners

For some projects, we rely on the expertise of our partners, including talented designers, developers and writers. Each one is an expert in their own right who brings skills and talent to the table that help our projects shine. Our partners allow us to hand-pick the best team for each project.
