Freelancer Overview

I am an experienced Data Labeling and AI Training professional with hands-on expertise across image, text, and audio datasets. I’ve worked on projects involving image classification, object detection (bounding boxes), and semantic segmentation using tools such as Label Studio and CVAT. In the field of NLP, I have performed text classification and Named Entity Recognition (NER), while also contributing to audio transcription and speech annotation projects using tools like Prodigy. My strong attention to detail, multilingual abilities (English, Persian, and Spanish), and commitment to data quality allow me to consistently deliver high-accuracy annotations under tight deadlines. I take pride in understanding the context and goals of AI models I help train, ensuring that my work contributes meaningfully to robust, real-world AI systems. I’m now looking to apply these skills to new, challenging projects through OpenTrain.
