Lilian Osumba

I am a detail-oriented Data Labeling Specialist with hands-on experience annotating images, text, audio, and video to support AI and machine learning initiatives.

I have completed multiple freelance annotation projects on platforms such as Appen and TELUS International, maintaining accuracy rates above 95% while adapting quickly to different project requirements and tools.

My strengths include image annotation (bounding boxes, polygons, segmentation), text labeling (NER, sentiment, categorization), audio transcription and tagging, and rigorous data quality assurance to improve model training outcomes.

I hold a Diploma in Computer Science, am fluent in English and Swahili, and I seek remote, flexible roles where I can apply strong attention to detail, time management, and collaborative skills to deliver reliable labeled datasets.
