Starfish Space
I currently work on flight software for Starfish Space, a startup building and operating satellites capable of docking with and servicing other satellites.
SpaceX
I helped with the design and operation of SpaceX's Starlink satellite mega-constellation from pre-alpha to ~10k satellites in orbit. I spent time building telemetry, real time simulation, and rendering software, while contributing to the design of the v1, v1.5, v2 mini, and v2 vehicles.
Mapbox
I worked at Mapbox for 5 years building open source cartography and navigation software.
Turf
Turf is a JavaScript library for spatial analysis. I started the project in 2013 looking for an efficient way to manipulate and visualize geographic data. The project has survived on the contributions from developers around the world.
