Freelancer Overview

I have extensive experience in data labeling across multiple fields, including finance, public relations (PR), human resources (HR), translation, image recognition, and related areas. Over the past three years, I have worked in both Portuguese and English, labeling data for a wide range of AI applications. My work has involved utilizing tools like Labelbox, CVAT, and Appen for tasks such as image annotation, text classification, and translation. I have developed strong skills in training AI systems with diverse data types, improving model accuracy across various industries.

Labeling Experience

Multilingual Text Classification for Finance

AppenTextEntity Ner ClassificationClassification

This project required labeling financial news articles in both Portuguese and English. The task involved classifying articles based on financial categories such as stocks, bonds, commodities, and market trends. Additionally, entity recognition was performed to identify companies, products, and financial terms. I also assisted in the translation of key terms and phrases to ensure accurate labeling across both languages.

In this project, I worked with medical images such as X-rays and CT scans, annotating regions of interest such as tumors, lesions, and other abnormalities. The task involved precise segmentation and key point labeling to identify and classify medical conditions. Annotations were cross-checked with radiologists’ reports to ensure high accuracy and reliable AI model performance.
