Problem

Lenders need to estimate credit default risk before approving a loan — but raw tabular data is messy, classes are imbalanced, and it is easy to build a model that looks strong offline yet fails under real decision constraints.

Solution

Credit Loan Risk is a personal data science project building a disciplined default-prediction workflow: clean data, auditable features, baseline models, and evaluation metrics that match the problem — not just accuracy on a skewed label.

Status

In development. EDA, feature design, and the first modeling experiments are underway. This page will gain concrete metrics and artifacts as the milestones land.

Highlights

  • End-to-end loan risk pipeline: ingest, clean, feature engineering, train/validate, and report
  • Focus on interpretable baselines and rigorous holdout evaluation before chasing complex models
  • Scoped for documentation and reproducibility first

Challenges

Outcomes

  • Reproducible notebook + script pipeline for training and evaluation
  • Written report tying model choices to business-facing risk tradeoffs
  • Portfolio-ready walkthrough of feature design and validation discipline

Demo

The interactive demo is not published yet. The spec below is current.
