Data analyst and master data specialist focused on improving data quality and automation.
What I'm looking for
I am a data analyst and master data specialist with hands-on experience improving data quality across large master datasets and cyber-incident collections. I focus on firmographic enrichment, validation, reconciliation, and automation to support accurate downstream analytics.
At Optimum Info Solutions I managed and analyzed 100K+ company records, built macro-based tools for bulk migration and AI-assisted validation, and integrated data from FactSet and Dun & Bradstreet to standardize corporate identifiers. My work reduced manual errors and improved master data reliability.
Previously at Institutional Shareholder Services I curated cyber-asset datasets with 98–100% accuracy, conducted corporate-structure analysis, executed peer Accuracy Reviews, and supported incident profiling for cybersecurity analytics. I also designed automation utilities and mentored new analysts to uphold team standards.
I work within Agile/Scrum teams, produce operational reports and executive slides, and apply root-cause analysis to fix recurring data issues. I seek roles where I can continue to scale data-quality processes, automation, and actionable reporting.
