About
I specialise in judging whether quantitative work is correct — and explaining why when it isn't. Two years as a student assistant and academic marker at North-West University (actuarial science, mathematics, statistics) meant evaluating thousands of solutions for accuracy, rigour, and clarity — the same skillset AI evaluation demands: spotting subtle errors, judging derivations, writing clear corrective feedback. Domains: probability, statistical inference, financial mathematics, derivatives pricing, optimisation, numerical methods. Credentials: six ASSA actuarial exemptions at 75%+, 2026 CFA Institute Research Challenge team. Tools: R, SAS, Python, Excel. Chess player, 1800+ rapid — error-spotting is a habit. Fully remote, consistent weekly hours, strong written English.
