Freelancer Overview

Passionate about artificial intelligence and data quality, I actively contribute to the annotation and structuring of datasets used for AI model training. I have developed skills in text classification, object detection in images, response evaluation for AI-generated content, and linguistic proofreading. I regularly use tools such as Label Studio, Labelbox, CVAT, and Doccano to ensure accurate, consistent, and guideline-compliant annotations. With strong attention to detail and a methodical approach, I focus on maintaining data integrity and annotation quality — key factors for effective machine learning models. My versatility allows me to work on multiple data types (text, image, video) and adapt to multilingual environments. I am motivated to contribute to innovative AI projects that combine precision, quality, and meaningful impact.

Labeling Experience

Video Annotation for Action Recognition

V7 LabsVideoBounding BoxAction Recognition

Labeled sequences of human and vehicle actions in short video clips for a real-time behavior detection project. Used bounding boxes and temporal tagging to mark action start and end frames. Collaborated in a small remote team using agile project tracking tools.

Smartphone Screen Defect Segmentation

Label StudioImagePolygonSegmentation

Annotated high-resolution 20MP smartphone screens, segmenting all defective pixels while excluding background. Managed pre-annotations, verified consistency across images, and performed QA to ensure precise segmentation for AI training. Annotated ~200 images per batch, with average speed 20–25 images/hour, including QA.

Image Annotation for Object Detection – EPI (Helmets, Vests, Gloves)

Label StudioImageBounding BoxPolygon

Annotated over 5,000 images for multiple short-term client projects, marking each EPI individually (helmets, vests, gloves) using bounding boxes and polygons. Ensured full inclusion of each object and exclusion of background, applied IoU metrics for quality assurance, and corrected pre-annotations when needed.

Audio Transcription & Quality Review for AI Speech Models

Internal Proprietary ToolingAudioSegmentationTranslation Localization

Between 2023 and 2024, I contributed to several audio annotation tasks involving French speech. My work included: • Word-level transcription of short and long audio clips • Detection of hesitations, mispronunciations, and speech errors • Segmentation of utterances into phonetic units • Quality verification and correction of pre-transcribed datasets • Rating ASR model outputs for accuracy and fluency I also participated in pilot tasks for ASR dataset preparation, where I reviewed children’s and adult speech recordings to improve model robustness.
