What I'm looking for

I’m looking to build finance models and evaluation systems for AI- and analytics-driven products—where methodological rigor, market realism, and clear measurement of outcomes are valued, and I can grow into roles spanning valuation, liquidity, and model governance.

I’m a Finance Specialist focused on rigorous finance problem design and AI evaluation. At xAI, I authored hundreds of CFA-level finance questions with gold-standard reasoning traces, then reviewed, stress-tested, and corrected LLM outputs across equities, fixed income, derivatives, real estate, and accounting. I also defined annotation guidelines and grading rubrics and QA-reviewed other tutors’ work to ensure consistency with industry expectations.

My background spans valuation, liquidity, derivatives, and data-quality work: I built 50+ professional financial-model workbooks from scratch, improved cash-flow forecasts with Python/VBA, and delivered Power BI/SQL liquidity dashboards. I previously worked as a Financial Analyst performing DCF, multiples, and comparable valuation, supported derivative pricing and stochastic models (e.g., BSM, Monte Carlo), and assisted credit-risk platform development. I bring a strong quantitative foundation from my Master’s thesis using Python regression analysis for equity risk premium modeling, and I’m a CFA Level I & II pass candidate.
