Freelancer Overview

I am a Business Management & Administration graduate with over four years of experience in digital marketing and a strong background in data annotation for AI training. I have worked as an Approved Data Annotator, where I contributed to the training and improvement of Spanish-language AI models by carefully annotating, reviewing, and validating linguistic data to meet rigorous quality and accuracy standards. My experience managing and optimizing digital advertising campaigns has given me a keen eye for detail and data quality, while my multilingual skills in English, Spanish, and Catalan enable me to work effectively on diverse projects. I am passionate about expanding my expertise in AI training data, especially in NLP and language-based domains, and am always eager to take on new challenges to further develop my skills.
