-
Foundations: Python, Statistics & Financial Data Literacy
6 weeksGoals
- Gain fluency in Python for data manipulation and basic modeling
- Understand core statistical concepts: distributions, hypothesis testing, correlation vs. causation
- Learn the structure of financial data: credit reports, bank statements, loan tapes, and income verification
Resources
- Python for Data Analysis by Wes McKinney (O'Reilly)
- Khan Academy Statistics & Probability course
- CFPB credit reporting educational resources
- Kaggle: 'Credit Card Fraud Detection' and 'Home Credit Default Risk' datasets
MilestoneYou can load, clean, and explore a real-world credit dataset using pandas and produce basic statistical summaries.
-
Credit Risk Fundamentals & Traditional Modeling
6 weeksGoals
- Learn the end-to-end loan underwriting process across mortgage, auto, and personal lending
- Build logistic regression and scorecard models (WOE/IV) for credit decisioning
- Understand regulatory frameworks: ECOA, FCRA, fair lending, and adverse action requirements
Resources
- Credit Risk Scorecards: Developing and Implementing Intelligent Credit Scoring by Naeem Siddiqi
- SAS or Python scorecard development tutorials
- FFIEC interagency fair lending examination procedures
- LendingClub historical loan data on Kaggle
MilestoneYou can build a compliant credit scorecard from raw application data and explain the regulatory logic behind adverse action notices.
-
Applied ML for Underwriting & NLP Document Processing
8 weeksGoals
- Train and evaluate tree-based models (XGBoost, LightGBM) and neural networks for credit scoring
- Build NLP pipelines using HuggingFace and OpenAI APIs to parse and classify loan documents
- Implement model explainability (SHAP/LIME) and generate automated adverse action reason codes
Resources
- Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow by Aurélien Géron
- HuggingFace NLP course and financial document classification tutorials
- OpenAI Cookbook: function calling and structured extraction examples
- AWS SageMaker credit risk model deployment workshop
MilestoneYou can deploy an end-to-end ML underwriting model that ingests borrower data, scores applications, generates explanations, and serves predictions via API.
-
Production Systems, MLOps & Fair Lending at Scale
6 weeksGoals
- Design production-grade ML pipelines with monitoring, drift detection, and automated retraining
- Implement comprehensive fair lending testing and bias mitigation techniques
- Build champion-challenger frameworks and A/B testing infrastructure for continuous model improvement
- Integrate LLMs for intelligent document workflows with guardrails against hallucination
Resources
- MLflow documentation and production tracking best practices
- Google 'Fairness Indicators' and IBM 'AI Fairness 360' toolkits
- Made With ML MLOps course (Goku Mohandas)
- Industry case studies from Upstart, Zest AI, and Blend on AI-driven lending
MilestoneYou can architect, deploy, and govern a complete AI underwriting system that meets enterprise reliability, fairness, and auditability standards.
Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
End-to-End Credit Scoring Pipeline with Explainable AI
IntermediateBuild a complete credit scoring system using LendingClub or Home Credit data. Train an XGBoost model, implement SHAP-based explanations for every prediction, generate adverse action reason codes compliant with ECOA, and serve the model via a FastAPI endpoint with input validation.
LLM-Powered Loan Document Parser
IntermediateCreate a system that ingests PDF loan documents (pay stubs, W-2s, bank statements), uses OpenAI or HuggingFace models to extract structured data (income, employer, account balances), validates extracted values against business rules, and flags low-confidence extractions for human review.
Fair Lending Audit Toolkit for ML Models
AdvancedBuild a comprehensive fairness evaluation framework that tests any credit model for disparate impact across protected classes, computes fairness-accuracy tradeoff curves, generates audit-ready reports, and suggests bias mitigation strategies. Use IBM AIF360 and custom statistical tests.
Real-Time Underwriting Decision Engine with Feature Store
AdvancedDesign and deploy a production-style real-time underwriting system using Feast for feature management, SageMaker for model inference, and Kafka for event streaming. Implement champion-challenger traffic splitting, latency monitoring, and automated model performance dashboards.
Automated Income and Employment Verification System
BeginnerBuild a pipeline that uses Plaid API to connect to borrower bank accounts, automatically detects income streams through transaction categorization, calculates stability metrics over time, and produces a verification report suitable for underwriting. Handle edge cases like gig economy income.
Multi-Product Underwriting Model Router
AdvancedCreate a system that routes loan applications to specialized models based on product type (personal, auto, mortgage), handles product-specific feature requirements, manages shared vs. product-specific data pipelines, and provides a unified decision interface with product-appropriate explanation formats.
