Public information,
made rigorous.
Research,
given form.
I build the systems between a source and a decision: research infrastructure, analytical tools, and software for the public interest.

Three systems.
Different questions. The same discipline.

Exercitus
The record.
The source.
The space between.
A registry of military exercises in the Baltic Sea region. Every date, participant, and personnel figure stays connected to its evidence.
Defender 2024
October 2026 snapshot.
As of October 2026.
Reported activity, with documented limits.
The question
How can reports on military exercises become records whose evidence can be inspected? A personnel count may describe a whole exercise, a national contingent, or a related programme. Those figures are not interchangeable.
The system
Language-model extraction, deterministic checks against source text, and human-signed corrections. Source passages stay alongside values; umbrella exercises and components retain explicit relationships and identifier histories.
Scope & limits
1,658 exercise editions, 2015–2026, drawing on 29 official websites as of October 2026. Coverage is uneven; this is reported activity, not a complete census or an escalation prediction system.
An earlier single-reviewer assessment found 85.5% of 379 judgeable registry values correct. A separate held-out extraction test found 91.3% of 126 values correct. These measure different things.

The city is full
of places to start.
Enter a postcode. Get a walkable round of places that hire off the street — and the rights information you need once you find work.
A city database, a weekly verification pipeline, and an interface built around the person on foot.
The question
Where can you walk in and ask for work in Berlin — and what are you owed once you do? A postcode becomes a walkable round, rather than another list of adverts.
The system
A city database answers searches locally. A weekly pipeline refreshes places, while an audit rebuilds the city from a second source to expose disagreements. Built end-to-end, including workers’ rights.
Scope
40,488 places, 96 Kiez pages, four interface languages. Figures from September 2026, not live counters.
03 / OSINTThresholdAn archived system. A more precise question.Archived researchDetailsClose
The work is in making it
possible to answer.
My background is in international relations and North American studies. I build the pipelines, interfaces, and analytical frames that let a question meet the evidence.
Keep the source close.
A useful record should let you inspect where it came from, not just accept the result.
Make uncertainty legible.
Disagreement, missing information, and failed tests belong in the system.
Build something usable.
The interface is part of the research. A finding matters more when someone can work with it.
