Freelancer Overview

I am a detail-oriented data analyst with hands-on experience in cleaning, transforming, and analyzing large datasets using tools like Excel, SQL, Power BI, and Python (Pandas). My background includes working on freelance projects where I extracted actionable insights from sales, marketing, and customer data, and developed interactive dashboards to support business decisions. I am skilled in data quality assurance, data visualization, and reporting, and I thrive on turning raw data into meaningful, structured information for further analysis or AI model training. With a strong foundation in cybersecurity and technical support, I bring an analytical mindset, accuracy, and a passion for high-quality data annotation to every project.
