Freelancer Overview

I have a strong academic background in business administration and technology, with experience working in fast-paced environments such as Ryte in Munich. My studies at the Technische Universität München and Universität Bayreuth have equipped me with analytical skills and attention to detail, which are essential for data labeling and AI training data roles. I am fluent in German, English (with Oxford CAE and DAAD certifications), and have knowledge of French, enabling me to work effectively with multilingual datasets. My experience in sales operations has honed my ability to manage data accurately and efficiently, and my ongoing studies in English and Mathematics further strengthen my logical and linguistic capabilities. I am eager to apply my skills to support high-quality data annotation projects in domains such as NLP and AI development. I have approximately 2 years of data labelling and AI training experience, mostly via online work platforms.
