Invisible Technologies • Freiberufler

Dec 2020 - Nov 2021 • 11 mos

At Invisible Technologies, I contributed to AI and data-operations projects supporting DoorDash, focusing on high-quality training data, data annotation, validation, and quality assurance. My work involved labeling and classifying data, reviewing merchant and menu information, auditing ads and promotions, fact-checking, identifying inconsistencies, and ensuring compliance with detailed project guidelines. I also supported AI model improvement through data quality checks, annotation consistency reviews, and evaluation of AI-generated content. This experience strengthened my expertise in AI data annotation, data validation, quality control, human feedback, and AI/LLM evaluation while maintaining high standards of accuracy, consistency, and attention to detail.
