Freelancer Overview

I have solid experience in data labeling and AI training tasks, including text translation (English–Portuguese), text evaluation, and image/object classification. I have participated in multiple projects involving LLM evaluation, content moderation, and quality assessment of model-generated responses. I have been working in the data field for many years and have over 10 years of experience in IT, with strong knowledge across different industries such as education (faculties/universities), internet service providers, and software development. My background working with structured data, combined with attention to detail and strong analytical skills, allows me to deliver accurate and consistent annotations.

Labeling Experience

Evaluation of AI-Generated Text Responses

Data Annotation TechTextText GenerationText Summarization

I evaluated responses generated by Large Language Models (LLMs), rating accuracy, coherence, and relevance according to project guidelines. Tasks included checking factual correctness, identifying hallucinations, assessing safety risks, and comparing multiple model outputs to determine the best response. I consistently followed annotation standards to improve model quality and behavior.

Image Classification and Object Annotation

Data Annotation TechImageClassificationObject Detection

I performed image classification and object tagging to support computer vision model training. Activities included identifying objects, labeling scenes, tagging visual attributes, and reviewing annotations for accuracy and consistency. I processed large batches of images while following strict guidelines and quality metrics to ensure high-quality training data for AI models.

English–Portuguese Text Translation and Review

Data Annotation TechTextTranslation Localization

I translated and reviewed English–Portuguese texts to support AI training datasets. Tasks included verifying grammar, improving fluency, ensuring semantic accuracy, and correcting model-generated translations. I also evaluated text quality based on project guidelines, checked for tone consistency, and delivered high-quality annotations in large batches.
