Hi, I'm Matt.

I love to tell stories on the web, taking data and shaping it into something compelling through analysis and visualization.

I've worked as a robotics engineer, was the lead developer of a web analytics reporting application with over 10,000 users, and have a degree in physics. Now I'm the co-founder of a mapping company.

My Recent Work

COVID in the Counties

April 2020

We all need to do our part to avoid catching and spreading COVID-19. Here, Brian Holdefehr and I attempt to visualize how well the places we all live are doing at preventing the virus from spreading.

Ramble Maps

January 2020

High resolution elevation maps of your favorite places to hang on your wall. Starting with the Green Mountains of my home state of Vermont. The data for our maps is gathered using LiDAR sensors. This lets us resolve terrain detail down to about 2 feet wide, which is 9x better than existing maps.

How To Communicate As You Scale Your Org

November 2019

Embracing a written culture can help your org get through growing pains as you scale from small to medium sized.

Inertial Navigation In Marine Robotics

An introduction to inertial navigation in marine robotics, from the sensors used to the mathematical tools needed to fuse that sensor data into a navigation solution

An Email-Only Authentication Scheme

October 2018

A post on bugbucket.io outlining a JSON Web Token based, email-only authentication scheme that I used for that application.


September 2018

BugBucket is a Github app that allows private repositories to open their Github issues to users outside of their organization. It is intended to provide a lightweight way for companies to manage user feedback, bug reports, and feature requests.

Beyond The Fat Arrow: Functional Programming In Javascript

April 2016

A quick survey of functional concepts and a discussion of the perils of mutating state and how you can use immutable data structures to protect against unwanted side effects in your javascript today.

Programmer Artist: LakeBrite at the ECHO Center

December 2015

LakeBrite is a 7,500 node, 3D LED matrix installed at the ECHO Center in 2015. As the first "programmer artist" for the installation, I helped design the interface to the LEDs as well as developed the first handful of data visualizations used in the 24ft x 9ft x 5ft display.

Improving The Weather On Twitter: Using NWS Data To Make Animated Radar GIFs

How I used National Weather Service data and imagery to make a network of twitter bots that post regional radar GIFs with improved palettes and projections.

Negotiating HTTP/2: ALPN And The TLS Handshake

April 2015

The HTTP/2 specification was approved on February 18, 2015 and implementation has already begun. In this post, I explain how HTTP/2 will be negotiated in today's web.

Mt. Mansfield Snow Depth

February 2015

A data visualization that allows users to compare the snow depth on Mt. Mansfield for a particular season against the historical record. This chart was used as an example of an effective visualization in "Good Charts" by the Harvard Business Review, was retweeted by Edward Tufte (who wrote the book on data visualization), and was shared by the Washington Post on their "Know More" blog.

wxGIF: Beautiful Radar Made For Twitter

January 2015

A network of 15 Twitter bots that tweeted animated radar GIFs every 2 hours (until I shut down the service in April 2017). I took static NWS images, changed the projection, basemap, and palette—making it color-blind friendly and more intuitive—and strung the images together into GIFs.

Lake Champlain Watershed

September 2014

A map of my home, the Lake Champlain Watershed. Published occasionally by VPR and printed full page by the Burlington Free Press on January 3, 2016. Full resolution PNG (for screen) and JPEG (for print).
