PROFESSIONAL SUMMARY
Analytical professional with 15+ years’ experience working across data science, system design, and senior
organisational leadership. Brings a multidisciplinary background spanning analytics, law, operations, and
technical delivery. Former regional director (300+ sta ) with hands-on experience in ML, data pipelines,
statistical inference, and geospatial QC. PhD in Law.

I excel in environments where: data is inconsistent or ambiguous, systems break at scale, decisions require
synthesis across domains, independent reasoning matters more than compliance. Looking for teams of
high-agency, rst-principles thinkers.
