About Me

I’m a Data Analyst and BI Developer with hands-on experience transforming raw, fragmented data into clean, structured, and decision-ready insights across government, e-commerce, fintech, and professional services.

My background started in government operations, where accuracy, documentation, and compliance were critical. From there, I transitioned into data-focused roles—handling large volumes of financial, operational, and customer data while building a strong foundation in validation, reconciliation, and reporting.

Today, I specialize in data cleaning, automation, and analytics. I work extensively with Excel, Google Sheets, SQL, Python, Power BI, Looker, Tableau, and BigQuery, building dashboards and automated workflows that reduce manual effort and improve data reliability. In recent projects, I’ve cut data preparation time by up to 40% by standardizing inconsistent datasets and automating repetitive processes.

Clients and teams rely on me to handle product, marketing, financial, and operational data—ensuring everything is accurate, structured, and ready for reporting, dashboards, or system integration.
