What I'm looking for

I'm seeking online AI training and annotation roles where precision, STEM subject-matter expertise, and consistent quality improve AI training workflows and deliver measurable impact.

I've supported Google data projects remotely for five years, evaluating AI-generated outputs, annotating structured and unstructured data, and providing RLHF feedback to strengthen model-training pipelines.

I bring Mathematics and Science subject-matter expertise to validate STEM-related AI responses, alongside hands-on work in data entry, cleaning, validation, prompt review, and content quality assurance. I consistently meet quality thresholds and deadlines while collaborating asynchronously with global teams.

Alongside AI work, I oversee academic quality assurance and teach Mathematics and Chemistry at Dr. Aggrey High School. I manage student data systems, produce performance reports, and coordinate national examination logistics.

My 10+ years as a STEM educator strengthen the analytical thinking, scientific reasoning, documentation, and precision I bring to remote AI training and annotation work.
