What I'm looking for

I seek remote or hybrid roles where I can apply annotation and QA expertise to improve AI models, work with collaborative cross-cultural teams, and grow toward broader ML or data roles.

I am a detail-oriented data annotator and AI trainer with over three years' experience labeling text, image, and audio datasets for global platforms such as Appen, OneForma, and TELUS International. I consistently achieve high accuracy through rigorous quality checks, follow complex annotation guidelines, and support multilingual projects while meeting tight deadlines.

Currently working in customer support, I combine strong communication and problem-solving skills with technical knowledge from a Master’s in Computer Science & Data Systems and certifications in AI training and machine learning. I collaborate effectively with cross-cultural remote teams and use productivity tools to improve workflows and model performance.
