Freelancer Overview

I am a reliable and detail-oriented professional with experience in audio production, workplace training, and general work services. I completed the UPWID Learnership Programme (2024–2025), where I gained supervised workplace experience at De Wit Motors, developing strong discipline, teamwork, and the ability to follow structured instructions in a professional environment. I also have hands-on experience in freelance audio engineering, including vocal recording, audio editing, mixing, and mastering using FL Studio and Cubase. In addition, my general work experience in cleaning, maintenance, and site support has strengthened my attention to detail, time management, and consistency skills that are important for AI data labeling and annotation tasks.
