I design domain-safe AI agents and forward indicators that surface policy & market shifts 3-6 months before official data. As a PhD economist and AI expert, I build forward-looking indicators, AI agents causal models that reveal economic turning points 3–6 months ahead of official statistics—and validate them with high correlation. I’ve uncovered billions in public-fund misuse by merging unconventional datasets, and my prompt-engineering playbooks now guide workflows inside multiple client firms. Engagements begin with a 60-minute diagnostic call, proceed through a scoped proposal, data audit, and milestone deliveries— memo, dashboards—culminating in a debrief and hand off.
