What I'm looking for

I’m seeking opportunities in AI data annotation and data quality.

At GlobalLogic, I test AI-powered medical imaging solutions and annotate and validate datasets for X-ray, Fluoroscopy, and CT applications.

I perform quality control on ML segmentation, landmark detection, and classification results, and work with medical datasets while following strict quality and compliance standards.

At MathPix, I labeled and validated image datasets, worked on a chemical data project focused on structural formula recognition, and refined mislabeled data.

I also annotated mathematical formulas, equations, and figures using LaTeX. I’m pursuing a Bachelor's degree in Cybersecurity at Odesa Law Academy and seeking opportunities in AI data annotation and data quality.
