Freelancer Overview

I have hands-on experience as a Data Annotator and AI Evaluator at Invisible Technologies, where I worked on large-scale training datasets involving image captioning, image-to-image (I2I), and image-to-video (I2V) evaluations. My role required consistently maintaining high accuracy while handling diverse edge cases, ensuring outputs aligned with strict annotation guidelines, and improving overall data quality for AI model performance. I have experience working at high speed without compromising precision, averaging 100–120 tasks per hour for standard tasks (1–1.5 min AHT) and efficiently managing more complex evaluations with longer review cycles. As a Computer Science student, I bring a strong understanding of the backend of AI systems, allowing me to go beyond surface-level annotation and better interpret model behavior, outputs, and inconsistencies. I’ve demonstrated strong work ethic and reliability by consistently working 11–12 hours per day on annotation workflows, showcasing both endurance and attention to detail. My combination of technical understanding, high throughput, and quality-focused evaluation makes me well-suited for demanding AI training and data labeling roles.
