At CrowdGen / Poliwag, I’ve contributed to more than 500 tasks across NLP, computer vision, and multimodal data. My work has achieved a 96% QA pass rate, with low rework and documented edge cases.

I’ve worked on RLHF ranking, prompt evaluation, and LLM evaluation, as well as NER and intent, sentiment, toxicity, and safety labeling.

As a Freelance Data Specialist, I conducted web research and data verification for international clients.

I’m fluent in English and Pidgin, and a native Hausa speaker. I hold a B.Sc. from Sokoto State University and certifications in Advanced Data Annotation & QA and AI Training & Content Safety Fundamentals.
