LoanGuard — AI Risk Management Audit

github.com/Marwakhot/-AI-Risk-Management-Audit

PROBLEM

AI loan-approval systems contain hidden biases and security vulnerabilities — violating fairness standards and exposing institutions to legal and ethical risk.

SOLUTION

A comprehensive fairness and security audit using the NIST AI RMF. Quantified gender & age bias via the 80% Rule, uncovered a 20% manipulation success rate on the age field, and produced a prioritized risk roadmap.

QuantRisk — VaR Validation & Capital Allocation

github.com/Marwakhot/QuantRisk-VaR-Validation

PROBLEM

Investment portfolios lack statistically validated risk quantification — making it impossible to set accurate capital reserves or meet Basel III regulatory requirements.

SOLUTION

Built a three-model VaR framework (Historical Simulation, Variance-Covariance, Monte Carlo) with Kupiec's POF backtesting. All models achieved 100% validation, recommending a $21,578 daily capital reserve at 99% confidence.
