Freelancer Overview

I am an experienced AI training specialist with over three years in data labeling, annotation, and quality assurance for image, video, and audio datasets. I have hands-on expertise with leading platforms such as Labelbox, CVAT, Scale AI, and Roboflow, and am skilled in annotating data for computer vision, NLP, medical imaging, retail, and autonomous vehicle projects. My work includes bounding box and polygon annotation, semantic segmentation, multi-object tracking using YOLO frameworks and DeepSORT, as well as audio transcription, speaker diarisation, and sentiment tagging for speech datasets. I excel at collaborating with machine learning engineers to define ontologies, create labeling guidelines, and deliver high-quality, scalable training data. My technical toolkit includes Python, JSON, cloud ML platforms, and a strong focus on maintaining high QA standards and inter-annotator agreement.

Labeling Experience

AI Training Specialist

LabelboxImageBounding Box

As an AI Training Specialist at DataBridge AI Solutions Ltd, I performed comprehensive image, video, and audio annotation for a variety of machine learning projects. My work included applying bounding box labelling, class annotation, multi-object tracking, and speech data annotation for automatic speech recognition (ASR) models. I maintained rigorous quality assurance, led guidelines development, and collaborated with ML engineers for ontology and benchmark design. • Performed annotation using Labelbox, CVAT, and Scale AI across diverse datasets • Applied YOLO v5, v7, and v8 for object detection model training • Led multi-object tracking with DeepSORT and ByteTrack for autonomous vehicle and surveillance data • Annotated and transcribed speech for ASR models, including sentiment and diarisation tasks.

Junior Data Annotation Specialist

RoboflowImageSegmentation

As a Junior Data Annotation Specialist at Turing Analytics UK, I focused on large-scale image, video, and audio annotation for object detection, segmentation, and NLP projects. I annotated images using segmentation masks and keypoint labels, transcribed audio data, and documented standards alignment. High annotation throughput and rigorous inter-annotator agreement goals defined my role. • Used Roboflow and Labelbox for monthly annotation of over 50,000 images • Produced segmentation masks, polygon, and keypoint annotations with VIA and CVAT • Performed video activity recognition, pose estimation, and object tracking • Transcribed and emotion-tagged audio data for NLP and voice AI training
