I make public information usable.
A public record can exist and still leave people unable to find a project, test a claim, or decide what to do next. I work across data, software, and institutional practice to close those gaps.
I map records to open standards, build publishing systems, and work with the people responsible for using and maintaining them.

New tool · Open Infrastructure Atlas
42,361 public projects on one globe.
Twelve governments and agencies publish their infrastructure projects as open data. I put every record on a single map and tested each location claim. Only 275 place a project exactly where the publisher said it is.
Writing and practice
What the records let us see.
These essays start with real records and practical questions: what can someone check, what remains hidden, and who can act on the answer?
Why public disclosure portals stop updating
A public portal can keep its address while the records behind it stop moving. Dated cases show where the publishing work breaks down.
What infrastructure projects must disclose after contract award
A signed contract starts years of construction, payments and maintenance. What should the public still be able to see?
Zambia's infrastructure data: one of six public checks can run
A published record opens six questions about a project. Missing answers mean different things, and each calls for a different response.
Malawi infrastructure portal: 162 records and no measured progress data
Malawi marks the M12 to Ludzi road complete. Its published record leaves most of the evidence needed to check that claim out of reach.
