What I'm looking for

I am looking for a role that fosters collaboration and innovation, where I can contribute to impactful machine learning projects and continue to grow my skills in data science.

I am an experienced Data Annotation Specialist with a strong background in NLP, computer vision, and sentiment analysis. Since 2022, I have worked remotely with Aya Data, where I labeled and organized datasets to meet machine learning standards, optimized annotation workflows, and supported cross-functional teams in resolving data inconsistencies. My expertise spans tools such as Labelbox, CVAT, SuperAnnotate, and V7, along with skills in metadata management, workflow optimization, and machine learning data preparation.

I hold a Bachelor’s degree in Information Studies and a Certificate in Data Science Administration from the University of Ghana. During my studies, I conducted research on metadata and its impact on search accuracy, and co-led the development of a digital repository for a local historical society.

I am passionate about using structured, high-quality data to improve AI systems and enjoy roles that combine technical problem-solving, collaboration, and continuous learning. Beyond data work, I am interested in advancing innovations in AI that create practical solutions for businesses and communities.
