Hi, I’m Kwame Walker Yirenkyi, a data annotation specialist focused on delivering high-quality datasets for NLP, computer vision, and sentiment analysis. I enjoy turning raw data into reliable, well-labeled training material that powers robust machine learning models.
I thrive in remote, cross-functional teams, optimize annotation workflows, and proactively address data inconsistencies to keep projects on track and accurate. When I’m not labeling data, I explore ways to improve data pipelines and collaborate with colleagues to share knowledge and best practices.
