CanadaWhat I'm looking for
I am an experienced AI data annotator with hands-on experience reviewing and labeling datasets to improve machine learning model performance. I focus on text-to-image evaluation, head-to-head model comparisons, and dataset quality checks to ensure training data is accurate and reliable.
My background includes completing large volumes of annotation tasks while maintaining strong attention to detail, flagging incorrect labels, and identifying visual mismatches and other model errors. I draw on prior customer-facing roles to communicate findings clearly and collaborate with teams to resolve issues.
I hold a B.Sc. in Biochemistry and a diploma in Microsoft Office tools, and I bring analytical thinking, pattern recognition, and consistency to every project to help build higher-quality AI systems.
