Freelancer Overview

AI Trainer with experience in language data annotation, transcription, and AI model improvement projects. Specialized in supporting the development of large language models through high-quality linguistic input, evaluation, and quality control. Key areas of expertise include: - Audio transcription (clean and verbatim) - Data annotation and labeling for NLP models - Prompt evaluation and response quality assessment - Linguistic validation and error detection - AI training data review and quality assurance Experienced in working on task-based, remote AI projects involving conversational data, structured and unstructured text, and multilingual content (native French, professional English). Strong attention to detail, consistency in guideline application, and ability to meet accuracy benchmarks and turnaround deadlines. Comfortable working within evolving annotation frameworks and adapting quickly to new tools and project requirements. Focus: delivering reliable, high-precision data to improve AI model performance, linguistic coherence, and contextual accuracy.

Labeling Experience

Video annotation & tracking specialist

V7 LabsVideoObject DetectionAction Recognition

Performed frame-by-frame annotation and object tracking across video sequences to train motion detection and behavior recognition models. Labeled key events, tracked moving objects across multiple frames, and applied temporal markers to specific actions. Maintained high precision in dynamic environments and ensured annotation continuity across sequences.

Computer vision data annotator

CVATImageBounding BoxEntity Ner Classification

Annotated and classified large image datasets to support computer vision model training. Tasks included drawing bounding boxes around objects, semantic segmentation, labeling object attributes (color, size, condition), and validating annotation accuracy. Ensured consistency across datasets by strictly applying taxonomy guidelines and conducting peer-review QA checks.
