Ben Carneiro — Software Engineer

Resume · Portfolio · Mastodon

I build data-heavy web apps — mostly mapping and geospatial stuff, using Python/Django on the backend and JS mapping libraries up front. I like taking big, messy public datasets (transit records, census data, crash reports) and turning them into something people can actually dig into.

Currently looking for my next role — happy to talk about any of the projects below.


Projects

roadway.report — Nationwide Vision Zero Map - repo

An interactive map of every recorded traffic fatality in the US (2001–2024), built on federal crash data.

  • Click any street and see every fatality recorded there, with filters across hundreds of variables the feds track
  • The backend API isn't tied to one region — other devs can build their own frontend for any part of the US using it
  • Takes a big, messy government dataset and makes it fast to search from the browser

censusmaps.org — Interactive Demographic Maps - repo

Free 3D demographic maps for any US metro — no GIS background needed.

  • Interactive maps you can make and share with just a URL
  • Export the GeoJSON layers to use in your own tools
  • Used by urban planners and demographers as a quick reference

transit.observer — US Transit Spending & Performance - repo

Explore transit spending and performance for any agency in the US, going back to 1985.

  • See capital vs. operating spend by agency and year
  • Compare service levels, ridership, and cost-efficiency across agencies over time

About

I like free software, public transit, databases, maps, and yeah, the electric scooters that litter the streets. I pick up new tools when a project needs them, not just to chase what's trendy.
