Freelancer Overview

I have hands-on experience in AI data labeling and annotation, specializing in both image classification and text translation tasks for machine learning projects. While working with Remotasks, I contributed to large-scale datasets used to train computer vision and natural language processing (NLP) models. My work involved labeling objects and scenes for self-driving and image recognition systems, as well as annotating and translating multilingual text data (English ↔ German/Spanish) to support language model development. What sets me apart is my combination of technical accuracy and IT background, which helps me understand how well-structured data impacts model performance. I am proficient in tools like Label Studio, CVAT, and LabelImg, and I apply strong attention to detail, consistency, and quality control in every project. My goal is to deliver precise, high-quality annotations that strengthen AI systems and ensure better real-world performance.
