What I'm looking for

I'm looking for remote AI data annotation, evaluation, prompt engineering, or quality-review work where I can apply multilingual language skills, detailed guideline interpretation, and reliable high-volume delivery.

I'm a trilingual data annotation and AI evaluation specialist based in Nairobi, Kenya, working across Swahili, English, and Kikuyu. Over the past two years, I've built hands-on experience in RLHF workflows, prompt engineering, and AI response ranking — evaluating AI-generated content for helpfulness, tone, and accuracy, and applying structured guidelines to keep quality consistent across high-volume projects.

Currently, I work as a Video Data Labeling Specialist at Atlas Capture, where I label each segment of an episode accurately, processing 400+ videos a week with a 95% QA accuracy rate. I also have annotation skills in bounding boxes, object tracking, and keyframe interpolation using tools such as CVAT. Alongside this, I work independently with multiple clients and platforms — including Perle (Winnow) and GoTranscript — on text annotation, transcription, content moderation, and fact-checking work, and I handle client communications reviewing written content for tone and factual accuracy.

I have a background in health sciences research, currently pursuing a nursing degree, and I've completed certifications in global health and health systems from Yale and Johns Hopkins — which gives me a useful edge when evaluating health-related datasets. I'm drawn to work that combines linguistic precision with analytical judgment, and I enjoy the fast-paced, detail-driven nature of annotation and evaluation work. I'm a quick learner on new browser-based tools (CVAT, Encord) and thrive working independently against tight deadlines.
