About

Professional summary

I am a Data Analyst and Data Operations Specialist with over four years of experience supporting technology, e-commerce, healthcare, and consulting teams. I work with large datasets to improve data quality, reporting accuracy, and operational decision-making.

I have hands-on experience in data cleaning, validation, transformation, reporting, dashboard development, and business analysis. I use Google Sheets, Microsoft Excel, Google Data Studio, pivot tables, advanced formulas, and automation techniques to turn complex data into actionable insights.

Throughout my career, I have processed and audited high-volume records while maintaining strong accuracy and compliance standards. My experience includes financial entries, marketplace listings, merchant SKUs, medical records, diagnostic codes, billing information, and CRM/ATS data.

I enjoy building streamlined workflows that reduce manual work, improve turnaround times, and make information easier for teams to access. I have developed automated templates, dashboards, logging processes, and data extraction workflows that improved reporting and operational efficiency.

I am detail-oriented, analytical, and comfortable collaborating with cross-functional and regional stakeholders. I am seeking opportunities where I can apply my data analysis, reporting, data operations, and administrative support expertise in a remote environment.
