ABOUT MAMADOU DIAITE
I am a finance professional with 13+ years of experience in FP & A, investment analysis, budgeting, forecasting, and KPI modeling. At American Express, I supported global business units by leading investment P&L management, partnering closely with Marketing and Product teams, and building financial models and reporting frameworks that shaped strategic and operational decision-making.My expertise includes developing forecasting and planning frameworks, evaluating ROI and payback for major initiatives, analyzing customer and product performance trends, and designing scalable KPI dashboards used by senior leadership.More recently, I’ve expanded into AI-driven finance as an AI Finance Expert with Mercor. In this role, I design complex financial scenarios, prompts, frameworks, and rubrics that help train, evaluate, and improve advanced AI reasoning systems. This work has strengthened my ability to translate real-world finance concepts into structured, high-clarity decision tools used by AI research teams.I’m passionate about combining finance, data, and emerging technology to solve business problems. Open to fractional FP & A work, financial modeling engagements, and AI-finance consulting opportunities where I can bring both deep domain expertise and innovative analytical thinking.
