About Me
I’m William. I like to build things, follow my curiosity, and create space for connection. My work has mostly been in software, but I’m just as drawn to leading teams, shaping products, and supporting community projects that help us live more regeneratively.
My Story
Over the years, I’ve worked on projects that span from small experiments to large-scale systems. What’s stayed constant is my love of learning, bringing people together, and shaping ideas into products that work in the real world.
What I Bring to the Table
Craft & Care
I like solving problems with clean, thoughtful code—and making sure what I build lasts.
Big Picture Thinking
I care about how technology and products fit into the wider story: the people using them, the teams building them, and the lasting impact they create.
Collaboration
I enjoy building teams where ideas can flow, people feel supported, and collaboration leads to better outcomes.
Always Learning
I’m always curious—whether it’s a new tool, a new perspective, or a new way of living.
