KenyaWhat I'm looking for
I am a detail-oriented Annotation Specialist with hands-on experience labeling audio, text, image, and video data for AI and machine learning projects. I consistently follow strict guidelines to produce high-quality annotations that support NLP, computer vision, and audio analysis pipelines.
I've worked remotely on client platforms including Upwork and Remotasks and held roles such as QA Data Labeler for RWS Group, where I reviewed and validated annotations to reduce error rates. I maintain accuracy rates above 95% on audio and other annotation tasks while meeting tight deadlines.
My experience spans SKU image annotation using CVAT, 3D object labeling, audio transcription and emotion classification, and dataset curation and preprocessing. I also contribute to improving labeling guidelines by documenting edge cases and collaborating with project leads and annotators to ensure consistency.
I hold a BSc in Industrial Chemistry and certifications including Salesforce Platform Administrator and data-focused programs from ALX Africa. I am adaptable, self-motivated, and passionate about improving annotation processes to enhance machine learning model performance.
