Anti-money laundering and fraud investigator moving from Teads ad operations, with crime investigations built to court standard.
What I'm looking for
At Metropolitan Police Service, I investigated crimes to court standard, including fraud by false representation. In one case, I traced bank-card withdrawals, obtained CCTV from a local council and retailer, and prepared evidence that supported the suspect being charged.
As a Detective Constable, I assessed risks to victims, built cases from multiple sources and conducted structured interviews. I prepared evidential case files and presented evidence at Crown Court and Magistrates’ Courts.
At Teads, I investigated discrepancies in live advertising campaigns, using data to find root causes and determine corrective actions. I also authored and maintained the Ad Operations handbook, documenting around 40 processes for daily team use.
I’m moving into anti-money laundering and fraud investigation, building on my investigative experience and introductory training in KYC, beneficial ownership, sanctions screening and transaction monitoring. I also use SQL, reporting tools and practical Gemini prompt engineering in my work.
