• Perform comprehensive validation of bank-wide models (including CCAR models) following SR 11-7 framework across a range of risk types, i.e., stress testing, credit risk, operational risk, and interest rate risk.
• Examine predictive power of forecast models and performed model assumption tests (models like Economic Capital, AI Predictive models, ESG Models) i.e.
• Breusch-Pagan, Durbin-Watson).
• Create coded programs using VBA and Excel, replicating results and conduct independent testing.
• Assessing quality of model outputs through back-testing against realized outcomes, benchmarking against alternative models and other relevant tests.
• Verify accuracy of model implementation, and reconcile large data inputs.
• Write model validation reports for distribution and presentation to senior management, model owners, auditors, and bank regulators.

• During my tenure with the Natwest Model Validation Project, I spearheaded ongoing validation efforts to uphold compliance with industry regulations and internal policies. As the Senior Validator, I provided strategic guidance on model validation processes, significantly reducing operational risks associated with inaccurate predictions or calculations.
• I conducted meticulous Backtests and Stress Tests on a variety of models, ensuring their robustness and reliability in different scenarios. Additionally, I actively contributed to report writing and test execution for several key models, leveraging my expertise to scrutinize and validate their performance.
• Collaboration was a cornerstone of my approach, as I worked closely with cross-functional teams to ensure alignment with regulatory requirements and to validate the assumptions made by Model Owners. This collaborative effort facilitated comprehensive validation exercises that bolstered the confidence in our models.

Furthermore, in accordance with risk policy, I played a pivotal role in determining the materiality of the models under review, providing critical insights into their significance within the bank's risk landscape. Through these endeavors, I contributed to enhancing the overall effectiveness and reliability of Natwest's model validation framework.
