Freelancer Overview

AI Language Data Annotation Specialist. I am a multilingual linguist and translator with experience in linguistic quality assurance, translation review, and multilingual content evaluation across English, Ukrainian, Russian, and Spanish. I hold a Bachelor’s degree in Translation and Interpretation, where I studied linguistics, terminology management, contrastive grammar, and specialized translation. My professional experience includes reviewing and evaluating multilingual content for accuracy, fluency, tone, and contextual meaning, as well as identifying and categorizing linguistic errors to ensure high-quality language output. In addition to my linguistic background, I have developed strong analytical and detail-oriented skills through experience in structured environments, including clinical laboratory technology training. I am experienced in working independently in remote settings, following strict guidelines, and providing structured feedback. My core strengths include data annotation, linguistic quality assurance, error analysis, and multilingual content evaluation, which align well with AI training data and data labeling tasks. Education includes Bachelor of Science, Arzobispo Loayza Institute (2023) and Bachelor of Linguistics, Lviv State University of Life Safety (2018). AI-training focus includes data types such as Text and labeling workflows including Evaluation and Rating.
