Banking Transaction Anomaly Detection
An anomaly detection engine for banking transactions that pairs machine learning with LlamaIndex retrieval and feeds enterprise fraud mitigation workflows.
Stack: Python, Machine learning, LlamaIndex
Problem
Fraud hides in a stream of ordinary transactions. Flags are only useful if they reach the team that acts on them.
What I built
- Machine learning models that flag anomalous banking transactions.
- LlamaIndex retrieval alongside the models.
- Integration with enterprise fraud mitigation workflows.
Stack
- Python
- Machine learning
- LlamaIndex
