Credit risk modelling and banking regulation, theory and practice.

📍 Zürich

Experienced manager with 12 years building and auditing credit risk models.

I am passionate about banking regulations, machine learning techniques, and the gap between what models say and what banks actually decide.

The website is organized as follows:

Notes

Breakdowns of banking regulation, credit risk and machine learning topics. One concept per entry, from first principles to the practical implication.

Two streams:

  • Banking regulation: Basel, CRR3, IRB, IFRS 9, stress testing, liquidity concepts.

  • Machine learning: models, regularization, calibration, validation, and the techniques that are relevant in a real credit risk work.

Tools

Interactive utilities for working through credit risk and machine learning concepts.

All tools are free, with reasonable usage limits to manage hosting costs.
