Freelancer Overview

I am a professional SEO copywriter with several years of experience creating high-quality, structured, and research-driven content, particularly in finance, business, and digital marketing. Alongside my writing career, I have gained hands-on experience in AI training and data annotation over the past two years, working with platforms such as Outlier and Alignerr. My work in data annotation includes labeling, evaluating, and improving AI-generated content with a strong focus on accuracy, clarity, and adherence to guidelines. Thanks to my background in copywriting and SEO, I bring a deep understanding of language, tone, and content quality, which allows me to deliver precise and high-quality annotations. I am detail-oriented, reliable, and comfortable working with complex instructions and large datasets.
