Senior Data Science & Analytics Leader | Principal Architect for $1B+ Remediations & Federal Consent Order Execution | Forensic Data Engineering | Strategic Management Advisor | Board-Ready Insights | “No Cold Handoffs”

Principal Data Strategist and Senior Data Science Leader with 16 years of experience architecting enterprise-scale decision systems for mission-critical challenges. While my background includes navigating $1B+ mandates and federal regulatory closures, my core expertise lies in designing end-to-end systems that ensure data integrity, stress-test decision strategies, quantify financial impact, and drive growth outcomes. I architect audit-ready pipelines that translate complex data into actionable, board-ready insights for the C-Suite and stakeholders at every level.

Portfolio Architecture: What These Systems Demonstrate

My GitHub portfolio is organized as a public proof layer for enterprise analytics architecture. Each project demonstrates a different point in the lifecycle from raw-data trust to decision strategy, remediation, liability modeling, and growth optimization.

Data Integrity
→ Reconciliation and Signal Detection
→ Credit Decisioning Strategy
→ Remediation Simulation
→ Liability and TVM Quantification
→ Growth / Retention Strategy

The common design pattern across the portfolio:

Governed Inputs
→ Diagnostic Logic
→ Scenario or Strategy Layer
→ Validation Evidence
→ Executive Narrative
→ Audit-Ready Handoff

This is the same philosophy I apply in regulated enterprise environments: do not simply produce outputs; make the underlying logic, evidence, assumptions, and stakeholder interpretation clear enough to trust.


Featured Portfolio Build: Enterprise Credit Decisioning Strategy Simulator

Enterprise Credit Decisioning Strategy Simulator

A two-module, portfolio-grade PostgreSQL credit decisioning simulator designed to demonstrate how governed synthetic application generation, pre-production strategy testing, archive-backed comparison, and executive-ready evidence can work together without exposing PII.

This is the newest addition to the portfolio architecture. It expands the lifecycle from forensic data integrity and remediation simulation into full credit strategy design, scenario testing, counteroffer governance, matched comparison, and executive decisioning evidence.

Module 1: Synthetic Application and Risk Modeling Engine

Builds a deterministic synthetic application population and risk foundation across:

  • product type
  • score band
  • borrower profile
  • requested exposure
  • APR proxy
  • monthly payment
  • payment-to-income ratio
  • synthetic estimated-PD proxy
  • LGD
  • Expected Loss

Campaign scope:

  • 19 governed scenarios
  • 50,000 applications each
  • 950,000 archived scenario rows
  • baseline product × score risk surface
  • scenario lever matrix
  • scenario Expected-Loss impact decomposition

Module 2: Credit Policy Strategy and Decision Outcome Simulation Engine

Consumes Module 1 synthetic outputs and applies governed strategy controls to simulate:

  • approvals
  • counteroffers
  • manual reviews
  • declines
  • approved exposure
  • approved Expected Loss
  • ordinary vs aggressive counteroffer path evidence
  • matched baseline / challenger strategy comparison
  • strategy frontier tradeoffs

Campaign scope:

  • 39 governed strategy runs
  • 50,000 applicants each
  • 1.95M archived strategy decisions
  • 20 matched comparison groups
  • 7 scenario families
  • strategy frontier analysis
  • baseline-relative challenger tradeoffs
  • selective vs aggressive counteroffer governance

Why this artifact matters

This project demonstrates:

  • governed credit strategy architecture
  • synthetic application and risk modeling
  • pre-production decision simulation
  • matched population comparison
  • archive-backed evidence discipline
  • parameterized policy and product controls
  • validation-ready QA workflows
  • executive dashboard storytelling
  • Expected Loss and affordability tradeoff analysis
  • counteroffer feasibility and governance design

This is not a dashboard-only artifact. It is a full-system decisioning simulator with SQL implementation, documentation, synthetic samples, QA outputs, campaign evidence, and executive dashboards.

Portfolio Philosophy

“No Cold Handoffs” — engineering zero-defect, audit-ready results so stakeholders internalize the underlying “why.”

My work is built around a simple principle:

A system is not complete when the output runs.
A system is complete when the logic, evidence, assumptions, controls, and downstream interpretation are clear enough for decision-makers to trust and act on it.

That philosophy shows up across my portfolio:

  • data integrity before modeling
  • signal detection before remediation
  • strategy testing before production change
  • quantification before executive decisioning
  • validation before stakeholder reliance
  • documentation before handoff

Data and Confidentiality Boundary

All public repository artifacts use synthetic, anonymized, or demonstration data.

These projects do not expose real customer data, production credit policy, proprietary remediation rules, confidential model inputs, regulated operational pipelines, or employer-owned decisioning logic. The repositories are designed to demonstrate methodology, architecture, validation discipline, and executive communication patterns in a public portfolio setting.
