What I'm looking for

I’m looking for an AI training/evaluation role where I can annotate and review data against clear guidelines, catch edge cases, and write structured feedback to improve model quality—using my AI API/web integration and strong documentation habits.

I’m a detail-driven AI Trainer and AI Training Specialist with hands-on experience annotating, labeling, and evaluating data against defined guidelines. I also build and test AI-integrated web applications, integrating AI APIs and processing user-uploaded datasets to return contextual, accuracy-checked insights.

In training and QA work, I review AI-generated outputs for accuracy, relevance, and quality—identifying edge cases and inconsistent patterns and writing structured feedback for improvement. I’ve applied strong data-quality discipline across 1,500+ records with zero tolerance for error, and I bring clear documentation and communication skills shaped by administrative work, teaching, and IT support/training.
