FinWatch — AML Detection Platform

A financial crime detection platform covering the full path from transaction to analyst decision.

Detection An XGBoost model registry feeding the scoring pipeline, with Prometheus observability across the system.
Process split The API, the profile ingestion worker and the DLQ retry worker run as separate processes, so each scales and restarts on its own.
Deployment A Docker Compose stack (Postgres, Redis, migrations, API, both workers) for local work, and systemd units for the servers.
Security API key authentication on every /api/v1 route, role-based access control, and audit records written for authenticated traffic.
Frontend A React.js dashboard with alert queues, case management views and evidence review interfaces.
