Open-source intelligence — geolocation, verification, sanctions and corporate research.

London, UK

I publish open-source investigations and build small tools that automate parts of the workflow. I'm interested in the intersection of OSINT, sanctions compliance, and conflict reporting. Currently working through Bellingcat's Online Investigation Toolkit and learning Python for investigative tooling.
