Fintech Scoring Boilerplate
Score risk like the banks do.
A production credit scoring boilerplate: feature engineering pipeline, scorecard model, decision engine, and explainability layer. The same patterns used in consumer lending and BNPL systems.
Tech stack
The Problem
Building a scoring system from scratch takes months of domain-specific work
Regulatory explainability (why was this declined?) is an afterthought in most codebases
Feature engineering for credit data requires lending domain knowledge most developers lack
What's Included
Everything you need to ship production-grade code
Feature Engineering Pipeline
Payment history aggregates, utilization ratios, vintage analysis, and behavioral indicators.
Logistic Regression Scorecard
Weight-of-evidence encoding, information value selection, and scorecard scaling.
Decision Engine
Rule-based policy layer over model score: hard declines, manual review buckets, auto-approve.
Explainability Layer
Top reason codes per decision — compliant with adverse action notice requirements.
Champion/Challenger
Traffic split infrastructure to run new models against production baseline.

Frequently Asked Questions
Does this require a specific data provider?
No. The feature engineering layer accepts any tabular input. Bureau integration stubs are provided.
Is this production-ready for regulated lending?
The patterns are production-grade but you must have a qualified compliance review before going live.
