What I'm looking for

I want to build automated, governed security metrics end-to-end—turning messy source data into scalable pipelines and decision-ready dashboards—where I can own architecture, collaborate across teams, and continuously improve reliability and impact.

I’m a Senior InfoSec Metrics Analyst focused on end-to-end delivery of data and analytics initiatives that turn cybersecurity data into clear, automated reporting. I coordinate business stakeholders and technical teams to deliver architecture, pipelines, and dashboards on reliable timelines.

At IQVIA, I designed an end-to-end Data Analytics architecture to improve scalability, governance, and platform integration, and I led the digitalization of key business metrics from scratch. I built automated data pipelines and recurring workflows, including data extraction, job scheduling, and email reporting, while integrating major security sources to strengthen visibility and reporting accuracy.

I work across modern analytics stacks—Hive, Cloudera (PySpark), Snowflake (including Gold Layer and dimensional models using Kimball principles), and enterprise dashboarding with Power BI and semantic modeling. Previously, I developed and optimized reporting and dashboards in Cyber Security and Digital Fraud teams (Power BI, Tableau, Qlik), supporting dashboard KPIs, data quality controls, and operational maintenance.
