AWS Usage & Cost Intelligence Dashboard

Cloud costs are the fastest-growing budget line — yet most teams lack real-time anomaly detection.

End-to-end pipeline processing 500,000 AWS billing records. IQR statistical anomaly detection flags $16,600+ in recoverable spend. Executive-ready visualizations delivered to finance and engineering leadership without analyst intervention.
