Applied AI · Finance · Open Source

Production-grade AI for fintech data teams:
clone it, run it, ship it.

Open source systems solving the most expensive data problems in financial services: regulatory compliance, customer risk, credit decisions and outhers. Each one ships with architecture, working code, and a path to production.

Each project includes
Working code on GitHub Architecture documentation Pluggable configuration
Project structure

Three artifacts per project, consistently.

Each project follows the same structure so you always know where to find what you need, whether you are evaluating the approach or running the code.

01
Overview
The business problem, how the system addresses it, what the output looks like, and what you need to run it.
02
Architecture
End-to-end pipeline diagram with every layer explained. Technical decisions documented with the reasoning behind each one.
03
GitHub
Modular Python code with a single configuration file. Clone the repository, set your API key, and run the notebook.
Impact

What these systems actually move.

Numbers pulled directly from each project's evaluation, not projections.

<10sec
Regulatory query time
Down from 20–40 minutes of manual search through FFIEC BSA/AML documentation. [GENAI-001]
1.19p.p.
Default risk reduction
Per one standard deviation increase in credit limit — the opposite of the common risk assumption. [CAUSAL-001]

Retention targeting
Top-decile churn scores find up to 4 times more churners than random outreach. [RISK-001]

BSA/AML Regulatory RAG
A retrieval-augmented generation system for querying BSA/AML regulatory documents. Answers compliance questions in plain English with citations down to section and page number. Uses hybrid semantic and keyword retrieval with temperature fixed at 0.0 for deterministic output.

Customer Churn with Explainability
A churn prediction pipeline for banking customers using gradient boosting with SHAP-based explainability. Each prediction comes with the features that drove it, making the output interpretable for risk committees and audit teams.

Causal Inference
Credit Intervention Analysis
A causal inference framework for estimating the effect of credit limit changes on default rates. Built with DoWhy and EconML to separate correlation from causation and answer the counterfactual questions risk teams actually need.
