Freelancer Overview

I have experience working with data entry, data validation, and annotation tasks that require high levels of accuracy and consistency. My background includes handling structured and unstructured datasets, verifying information quality, cleaning datasets, and organizing records for reporting and analysis. I am comfortable using tools such as Microsoft Excel, Google Sheets, REDCap, and ODK, and I understand the importance of following annotation guidelines, maintaining confidentiality, and meeting quality standards in data-focused projects. In addition, I have supported projects involving data analysis and digital record management, which strengthened my attention to detail and problem-solving skills. I am able to learn new platforms quickly, work independently, and manage repetitive tasks while maintaining accuracy. My combination of technical skills, analytical thinking, and reliability enables me to contribute effectively to AI training and data labeling projects that require precision and consistency.
