Experience behind quantitative capital and risk solutions that stand up to scrutiny.

Client challenge: A major banking integration required duplicate methodologies, models, governance structures, and infrastructure to be combined without disrupting regulatory or internal delivery.

Role and contribution: Led methodology integration, model-change planning, validation coordination, stakeholder alignment, and the controlled retirement of duplicate models and infrastructure.

Delivery scope: Integration strategy, quantitative methodology, implementation oversight, governance, cross-functional coordination, and team leadership.

Value delivered: Delivered key integration changes and retired duplicate models and legacy infrastructure materially ahead of plan, enabling earlier decommissioning and reducing maintenance effort, transition risk, and external-support dependency.

Client challenge: Credit-risk models and stress tools needed to connect portfolio behavior, regulatory parameters, RWA, and capital planning through a more consistent and reproducible framework.

Role and contribution: Contributed to IRB-standard PD and LGD development and validation and built automated methods for default-rate, parameter, and RWA stress testing.

Delivery scope: Quantitative methodology, calibration and validation analysis, scenario translation, R-based implementation, documentation, and stakeholder presentation.

Value delivered: Improved the consistency and repeatability of credit-risk assessment, stress analysis, and capital planning while creating reusable tools for execution and reporting.

Client challenge: Statistical and expert-based rating models required independent challenge, repeatable testing, and management-ready evidence across low-default and specialist credit portfolios.

Role and contribution: Performed quantitative validation and designed SAS-based monitoring, reporting, and documentation for recurring model oversight.

Delivery scope: Discrimination and calibration assessment, stability analysis, benchmarking, monitoring design, technical documentation, and presentation to management and control functions.

Value delivered: Strengthened model transparency, repeatability, challenge, and governance readiness across wholesale and specialist credit portfolios.

Client challenge: Stress testing required a more consistent connection among quantitative models, material-risk assessment, scenario design, expert judgment, controls, and management use.

Role and contribution: Redesigned and implemented a common framework spanning quantitative modeling, vulnerability analysis, expert workshops, documentation, controls, and governance.

Delivery scope: Methodology, implementation, expert engagement, validation preparation, legal-entity alignment, management communication, and recurring execution.

Value delivered: Established a validation-ready and governed framework across Group and a major Swiss legal entity, improving consistency, transparency, and repeatability.

Client challenge: Capital, stress-testing, and limit-setting processes used inconsistent assumptions, creating duplicated conservatism and a fragmented management view.

Role and contribution: Aligned methodologies, scenario interpretation, reporting, and governance across risk appetite, economic capital, regulatory capital, and stress testing.

Delivery scope: Methodology alignment, impact analysis, senior stakeholder engagement, governance design, and coordination across Risk, Finance, capital reporting, and business experts.

Value delivered: Reduced double counting, improved comparability across capital views, and gave management a more coherent basis for risk-appetite and capital decisions.

Client challenge: A broad portfolio of capital and stress-testing models required consistent performance monitoring, issue prioritization, and evidence for recurring governance and validation.

Role and contribution: Established quantitative metrics, qualitative review, management reporting, documentation, issue tracking, and reusable validation evidence.

Delivery scope: Monitoring design, threshold and metric definition, model-owner coordination, reporting, validation engagement, governance, and remediation prioritization.

Value delivered: Embedded a common monitoring framework across a broad model portfolio, improving early-warning capability, governance consistency, issue prioritization, and validation readiness.

Client challenge: Recurring stress-testing production depended on fragmented spreadsheets, legacy code, manual handoffs, and separate reporting processes.

Role and contribution: Built modular R workflows covering data checks, model execution, benchmarking, sensitivities, report generation, documentation, and controls.

Delivery scope: Process diagnosis, data controls, quantitative implementation, automated reporting, operating procedures, documentation, and team adoption.

Value delivered: Freed significant specialist capacity, generated material recurring savings, reduced manual error and reporting risk, and created a controlled process the wider team could operate and extend.

Client challenge: Risk and Finance needed a transparent way to connect macroeconomic scenarios with default rates, credit-risk parameters, RWA, and capital-ratio thresholds.

Role and contribution: Designed direct and reverse stress-testing methods and implemented reusable analytical tools in R.

Delivery scope: Scenario translation, default-rate and parameter modeling, RWA and capital analysis, reverse threshold identification, automation, and management presentation.

Value delivered: Enabled repeatable scenario-based capital analysis and identification of critical conditions, giving management a clearer view of credit-risk resilience.

Client challenge: Exceptional macroeconomic conditions exposed stability limitations in operational-risk stress models across Group and major legal entities.

Role and contribution: Designed and implemented permanent methodology enhancements combining quantitative analysis, expert assessment, scenario evaluation, governance, and validation support.

Delivery scope: Root-cause analysis, methodology redesign, implementation, sensitivity assessment, documentation, stakeholder alignment, and controlled production transition.

Value delivered: Replaced temporary treatments with a durable solution, improved model robustness under extreme scenarios, and reduced the need for exceptional manual intervention.

Client challenge: Operational-risk capital and stressed-RWA treatment had to reflect the Basel III transition consistently across capital, stress testing, reporting, and governance.

Role and contribution: Led quantitative methodology, impact analysis, implementation, and cross-functional alignment with capital, Finance, reporting, and governance teams.

Delivery scope: Regulatory interpretation, methodology design, impact assessment, implementation planning, testing, reporting alignment, and governance.

Value delivered: Implemented the transition methodology ahead of the rule change, improved consistency between capital and stress-testing frameworks, and gave management earlier visibility into the new treatment.

Client challenge: U.K. ICAAP delivery required local prudential needs to be met without duplicating Group methodology, implementation, documentation, and controls.

Role and contribution: Aligned quantitative modeling, expert-based material-risk assessment, local requirements, documentation, governance, and recurring delivery within a shared architecture.

Delivery scope: Methodology alignment, local requirement assessment, model implementation, expert engagement, documentation, governance, and recurring execution.

Value delivered: Reduced duplication, strengthened local-to-Group consistency, and enabled controlled, repeatable ICAAP delivery through a common methodology and governance structure.

Client challenge: Litigation risk was assessed through overlapping legal, accounting, risk-appetite, and prudential capital lenses, creating inconsistent treatment and duplicated conservatism.

Role and contribution: Initiated and led a governed methodology aligning legal judgment, accounting treatment, quantitative loss estimation, risk appetite, and capital use.

Delivery scope: Cross-functional methodology leadership, stakeholder coordination, governance, documentation, and integration into recurring capital and stress processes.

Value delivered: Established one repeatable cross-functional approach, removed overlapping treatment, and improved the consistency and decision usefulness of litigation-risk and capital assessments.
