About

Professional summary

I am a Financial Operations and Analytics professional with five years of experience at Citigroup supporting securities and derivatives operations across Latin American markets.

I specialize in automated KPI reporting, business intelligence, operational performance analysis, and process improvement. I transform data from multiple sources into reliable, executive-ready reports, dashboards, and actionable insights.

I independently designed an Excel-based automated reporting solution using Power Query, Power Pivot, and DAX that reduced reporting preparation time from approximately three hours to five minutes. This solution supported consistent reporting across six LATAM markets.

I have hands-on experience with advanced Excel, Power BI, data modeling, DAX, SQL fundamentals, data validation, trend analysis, exception investigation, and reporting automation. I also document business requirements and collaborate with Operations, Business, and Technology stakeholders.

I bring a control-focused mindset developed in financial operations, including securities, derivatives, reconciliation, and SWIFT-related workflows. I am seeking a remote Business Intelligence, Reporting, or Operations Analyst role where I can improve data quality, reporting efficiency, and business decision-making.

Experience

Career history

Securities & Derivatives Analyst Citigroup

I architected and maintained an automated KPI reporting solution using Excel, Power Query, Power Pivot, and DAX. The solution reduced manual report preparation from approximately three hours to five minutes, a 97% reduction, and enabled scalable reporting without dedicated development resources.

I own end-to-end operational performance reporting for six LATAM markets, consolidating, cleaning, and transforming multi-source data into weekly, monthly, and year-to-date reports. I design data models, DAX measures, dashboards, and presentations; perform trend, anomaly, and exception analysis; reconcile reporting inputs; and implement validation checks. I also document business requirements and partner with Operations, Business, and Technology teams on reporting enhancements in a control-focused securities and derivatives environment.

Cybersecurity Consultant Perseus Information Security Consulting

I evaluated client compliance programs against ISO 27001, NIST 800-171, CMMC, and TISAX frameworks. I translated assessment results into executive-facing reports and risk recommendations.

I collected and analyzed program performance data to support evidence-based findings, compliance assessments, and stakeholder reporting.
