I verify critical information before it becomes a costly mistake.

I work on cases where data looks credible but isn’t. When sources conflict, claims are difficult to prove, or decisions depend on what is actually true — that’s where I come in.

I specialize in source verification, due diligence, and investigative analysis. My work focuses on identifying unsupported claims, circular sourcing, false attribution, and fabricated narratives, and turning fragmented or inconsistent data into evidence that can be relied on.

I have over 20 years of experience working with primary and secondary sources across multiple jurisdictions — including archival records, legal documents, public databases, and non-digitized materials. I operate in situations where automated checks and standard due diligence are not enough.

My work includes practical due diligence in low-transparency environments, with direct experience verifying ownership structures, transaction chains, and investment-related data in the UAE real estate sector.

One of my investigations uncovered a fabricated narrative supported by interdependent published sources, which led to the removal of four interconnected Wikipedia articles — a case involving circular sourcing and constructed evidence systems.

My background includes long-form, primary-source research: two peer-reviewed monographs (600+ pages each) and nine peer-reviewed research papers.

I am typically engaged when the question is not what is written, but what can actually be proven — and whether the available information can be trusted.
