Public sources only
Open-source intelligence means turning publicly available information into answers. No breaking in, no private databases, nothing behind a login I am not entitled to.

Connection beats collection
Anyone can collect. The skill is in the joins: the same username on two platforms, a registration that names a person, a timestamp that contradicts a story. I build for relevance, not volume.
Evidence has to be checkable
Published records live in append-only, tamper-evident histories with SHA-256 hash manifests, so anyone can verify that nothing changed after the fact.
AI is a tool, not an authority
I use AI-assisted development every day. Generated code gets reviewed and tested, never trusted blind.
Privacy is maintenance
The same techniques that map a fraud network can expose an ordinary person. That is why the privacy side of this work matters as much as the investigative side, and why I publish tools anyone can use for free.
