As a Contract Transcriber on projects for ZAMBART, University of Zambia, and Sigma AI, I transcribed Tumbuka and English focus group discussions and in-depth interviews for academic and public health research. I consistently achieved more than 99% accuracy across 100+ hours of audio.

I followed research protocols for speaker differentiation and formatting, and used verbatim and clean-read styles to improve transcript clarity. I also worked with research teams to maintain confidentiality and meet strict deadlines.

In AI data annotation, I labeled and reviewed datasets, followed detailed guidelines, and carried out quality checks based on feedback. As a Virtual Assistant & Customer Support Contractor, I handled administrative tasks, scheduling, documentation, calendars, and customer inquiries.
