Data Collection

Freelancer Overview

I have over four years of experience in information technology, with a strong background in data analysis, database management, and supporting data-driven projects. My roles have involved leading data collation and analysis efforts, particularly during my time as an IT Analyst for a major presidential campaign, where I generated actionable insights to guide strategic decisions. I am skilled in Python, C++, and database tools, and have experience managing and maintaining large datasets to ensure data quality and reliability. My technical expertise also extends to cloud platforms, automation, and collaboration with cross-functional teams to deliver accurate and efficient data solutions. I am eager to apply my analytical skills and attention to detail to support high-quality data labeling and annotation for AI and machine learning projects.
