What I'm looking for

I’m interested in applying my education background to AI-driven learning products.

I reviewed and labeled first-person video footage for AI model training, identifying objects, surfaces, and hand-object interactions.

For egocentric video annotation, I applied atomic action labeling standards to turn complex activities into structured, machine-readable annotations. I completed training modules and quizzes on annotation guidelines to maintain consistency and accuracy.

As a survey data annotator, I reviewed, coded, and validated responses for accuracy, consistency, and completeness ahead of analysis. I used structured annotation frameworks to categorize responses and support reliable data-driven decision-making.

My education and political science background also includes teaching SS1 Government at Model Secondary School, Nsukka, and JSS1 Social Studies at St. Charles College, Opi, Nsukka. I prepared lessons, assessed student performance, and adapted teaching to different learning paces.
