Inspiration
Financial crime teams review thousands of alerts but still miss coordinated fraud rings. I wanted to shift investigations from transactions → networks → action.
What it does
Tasvi identifies coordinated account behavior, assigns explainable risk scores, and surfaces a priority investigation queue so analysts know who to act on first—and why.
How we built it
Multi-source transaction data is unified, enriched with graph-based risk intelligence, exported as Hyper files, and investigated through Tableau Cloud dashboards.
Challenges we ran into
Balancing realistic data volume with clear, human-friendly investigation workflows—showing meaningful risk without overwhelming the investigator.
Accomplishments that we're proud of
Built a pipeline-first system, used Hyper API over CSVs, and turned Tableau into an action-oriented investigation command center.
What we learned
Effective fraud detection depends on relationships, not rules—and trust comes from clear explanations, not black-box scores.
What's next for Tasvi (Financial Crime Investigation Center)
Near-real-time ingestion, automated alerts, deeper network visualization, and enterprise-scale investigation workflows.
