AI data specialist focused on annotation, QA, and multilingual evaluation.
What I'm looking for
I am a detail-oriented AI data specialist with extensive experience annotating, labeling, evaluating, and performing quality assurance on text, audio, image, and video datasets to support AI/ML model development. I deliver accurate, consistent outputs in remote and flexible environments and have advanced English proficiency (C1).
As a freelancer and remote contributor to platforms such as Remotasks, Microworkers, ParetoAI, Rev, Scribie, and babbleaudio, I have executed data collection, preprocessing, object tagging, classification, content moderation, and pairwise comparisons to measure and improve model accuracy. I manage multiple projects simultaneously while meeting deadlines and maintaining strict guideline compliance.
My background in scientific training and nursing studies strengthens my analytical, critical-thinking, and attention-to-detail skills, which I apply to ensure dataset integrity and improve model reliability through effective error detection and linguistic evaluation.
