Lewis Obinchu

I am an accomplished Data Annotator, Transcriptionist, and Editor with over seven years of experience delivering high-quality annotated datasets, accurate transcriptions, and polished digital content for AI and educational projects. I combine linguistic training with technical annotation tools to ensure precision and consistency across large-scale data workflows.

My work spans collaborations with AI engineers, supervision of labeling workflows, and mentorship of new team members, with achievements including maintaining 99% transcription accuracy and improving workflow documentation. I have supported Text-to-Teach initiatives at TVET institutions in Nairobi and Kericho, contributing to the digitization of education and AI readiness.

With advanced study in artificial intelligence and linguistic computing, multiple industry certifications, and hands-on experience with tools like Labelbox, CVAT, Appen, and Prodigy, I bring a disciplined, ethical approach to data quality, AI dataset creation, and content development.
