Profile

Performance-driven marketing organization relying on call-based conversions and lead generation

Project Background

The client manages large volumes of inbound and outbound calls tied to marketing campaigns, where performance visibility and quality control are critical.

The challenge

Marketing performance was difficult to monitor in real time due to the volume and variability of call data.

This resulted in:

  • Limited visibility into sudden drops or spikes in performance
  • Delayed identification of campaign or channel issues
  • Difficulty detecting low-quality or fraudulent leads
  • Reliance on manual review and delayed reporting

There was a need for a system that could automatically detect anomalies and surface meaningful signals across large datasets.

What we built

We designed and deployed an anomaly detection system focused on identifying unusual patterns in call and campaign performance data.

The solution included:

  • Data pipelines aggregating call data, campaign inputs, and performance metrics
  • Machine learning models trained to detect deviations from expected behavior
  • Real-time monitoring and alerting mechanisms
  • Integration with reporting systems to provide actionable insights

The system was designed to operate continuously and adapt to changing campaign patterns.

Impact in practice

The implementation enabled a more data-driven and responsive production environment:

Earlier detection of performance anomalies

by identifying deviations across call volumes, conversion rates, and campaign metrics

Improved campaign optimization

through faster identification of underperforming channels and segments

Better lead quality visibility

by surfacing patterns associated with low-quality or inconsistent traffic

Reduced reliance on manual monitoring

through automated detection and alerting systems

Technologies used

Several technologies were used in order to deliver this project for the client, among which:
