What I'm looking for

I seek an AI training or data quality role where I can apply multilingual annotation, data validation, and model-improvement skills within a collaborative, growth-focused team.

I am a highly motivated Computer Science graduate with practical experience in AI training, data labeling, and multilingual data evaluation. I graduated with honours (Master's and Bachelor's in IT - Computer Sciences) and focus on delivering accurate, high-quality datasets to improve model performance.

I have hands-on experience with text, image, video, and audio annotation, image segmentation and classification, captioning, transcribing, and linguistic analysis. I combine technical skills in front-end web development, SQL and database management with strong attention to detail and analytical thinking to ensure data integrity and validation.

I am eager to apply my experience in multilingual evaluation (Ukrainian, Russian, English) and my familiarity with generative models and LoRA training to help teams improve AI model quality, accuracy, and real-world performance.
