Hi, I'm Olga Quintela. I am an experienced research and AI training professional with 12+ years in web research and project delivery. I specialise in large-scale AI training data projects, including millisecond-level speech labeling and voice activity detection, evaluation of AI-generated images, pass/fail quality assessment with issue categorization, and linguistic QA and remediation of bilingual (PT/EN) conversational datasets for ASR. I enjoy collaborating with engineering teams, rapidly mastering new annotation tools, and working 100% remotely across time-zones. I have experience validating authentic code-switching, enforcing language ratio and domain accuracy in customer service scripts for enterprise-grade AI models. I also contribute as a freelance researcher and data curator, bringing strong communication skills and a detail-oriented mindset to every project.…Hi, I'm Olga Quintela.
