Work History
Data Scientist
Randstad Digital LLC (Verizon Wireless)
Irving , TX
2019.11 - Current
- Developed and deployed a Random Forest machine learning model to minimize fraud attacks during customer login flows, resulting in a remarkable 45% reduction in attack occurrences.
- Created an unsupervised clustering ML model to minimize fraud attacks during customer registration and forgot password flows, resulting in a significant 65% reduction in attack occurrences.
- Responsible for log investigations of flagged transactions and reports that showed potential suspicious or fraudulent activity.
- Participated in group discussions with team members to develop new ways to combat fraud.
- Developed weekly and monthly charts and statistics for stakeholder meetings.
- Owned the Customer Authentication reporting projects.
- Created dashboards and alerts for the internal teams to monitor fraud activity and take immediate actions. Reduced the false positive alerting by 47% by using the IQR techniques and also increased visibility of possible threat.
- Envisioned and proposed highly efficient dashboards with the capacity to retrieve millions of records spanning 1-2 years within seconds, which improves system efficiency and data accessibility.
- Collaborated cross-functionally with other teams to develop dashboards to monitor authentication metrics and analyze fraud spikes and anomalies, which resulted in avoiding threats before they occur and finding any bugs in the system.
- Partnered with other teams on data migration and replication tasks.
