Hi! I’m Lou.

I’m an open-source software developer, designer and civic technologist based in New York City. With a background in urban design and architecture, I focus on user experience and product leadership for tools in placemaking and community engagement. Here are some of my projects.


An interactive tool that empowers citizens to create their own street designs.


Tangram Play

Web-based editor for Tangram, Mapzen’s graphics rendering engine for digital maps.


Civic Seed

A multiplayer game designed to teach students how to become effective contributors to local communities.


The open data portal for the City and County of San Francisco was redesigned to improve data access.
