Najib Tackie
@najibtackie
I evaluate and annotate multilingual AI data to improve reliable language models.
What I'm looking for
I've evaluated more than 4,500 multilingual and mixed-language AI datasets for Human Signal, assessing instruction adherence, logical consistency, reliability, harmful content, and policy violations.
For OneForma and Amazon SageMaker Ground Truth, I transcribe and segment Akan audio for AI training at a 98%+ quality target, supporting speech recognition and NLP for low-resource African languages. I also annotate text and images using Label Studio, CVAT, and Labelbox.
My background in computer science, research, operations, judicial documentation, and remote guideline-driven work helps me deliver accurate, structured outputs while handling sensitive data responsibly.
