Freelancer Overview

I have extensive experience in data entry, data analysis, and data encoding roles, working on US-based projects and supporting various industries. My background includes hands-on work as a Data Analyst and Data Encoder, where I ensured data accuracy and quality for large-scale projects. I am highly skilled in MS Office, particularly Excel and its formulas, and have strong typing skills (up to 80 WPM) that enable me to efficiently handle high-volume data tasks. In addition to my professional experience, I have contributed to AI and Web3 projects, providing high-quality English speech data to improve Automatic Speech Recognition (ASR) technology and participating in platform testing and feedback for product improvement. My ability to multitask, attention to detail, and commitment to delivering reliable training data make me well-suited for data labeling and AI training data roles.
