Arnav Sahai

Data, AI, and cyber-risk analyst for business, economics, and policy decisions

I turn messy operational, market, and risk data into decision-ready analysis for hiring managers evaluating business analyst, data analyst, cybersecurity analyst, economics analyst, and quantitative analyst roles.

My work spans quantitative modeling, AI-assisted analytical tooling, cyber and technology risk frameworks, and policy-facing deliverables- backed by a Computer Science foundation, a Columbia SIPA MPA, and client-facing consulting experience including Accenture.

Recruiters will find evidence in client reports, reproducible research, and shipped analytical products rather than generic claims.
