Chinedu Caleb

I’m a dedicated Data Annotator, Translator, and AI Expert with academic training in Computer Science and Data Science. I earned an M.Sc. in Data Science from the University of Lagos and a B.Sc. in Computer Science from the University of Lagos.

In my current role as an AI Data Specialist at Lagos Technology Solutions (2023–Present), I apply my expertise to produce reliable, high-quality AI datasets. Previously, I worked as a Senior Data Annotator at Digital Data Solutions Ltd. (2021–2023), building depth in data labeling and evaluation workflows.

I focus on AI data labeling, model evaluation, NLP workflows, and quality assurance, with an emphasis on multilingual content review. I aim to turn complex requirements into accurate, usable data that helps models perform better.

I also bring translation and content review experience from my freelance work (2019–2021), strengthening my communication and attention to detail. My certifications include Google Data Analytics, IBM Data Science, and Microsoft Azure AI Fundamentals (AI-900), which support my practical, results-driven approach.
