About Simon Cavalletto

Hello! I’m Matthew Simon Ryan Cavalletto, the developer behind Green Thumb Software. I started developing dynamic websites in the early 1990s, just as the Internet began to take off as a platform for commerce, publication, and communication, and I’ve been working in various corners of the industry ever since.

My experience includes stints as a freelancer, as an independent contributor, as a team lead, and as a startup co-founder — sometimes looking at the big picture and at other times down in the trenches making sure the details are done just right.

In the Public Interest

Over the last fifteen years, most of my work has been in the realm of political advocacy, online campaigning, social benefit groups and non-profit organizations, and I’ve found these projects more rewarding than churning out yet another e-commerce solution or finding new ways to push out advertisements.

A decade of that period was spent as a member of the team that built ActionKit — originally as a small company named We Also Walk Dogs, now part of NGP/VAN and Bonterra. Along the way, I contributed to features across the entire scope of the system, including creating some of the product’s major capabilities including the point-and-click query builder, and fielded front-line support requests from nearly every organization that used the platform.

More recently, I’ve moved on to working independently for some of those same groups to help them get the most out of the ActionKit platform.

Why “Green Thumb” Software?

In recent decades, I’ve taken up urban gardening — creating a tiny oasis of green in the narrow strip of sidewalk outside my apartment building here in New York City — and in addition to contributing a name for this website, this pastime has also provided me with a metaphorical framework for thinking about the endeavor of building a modern online system.
