Project details
You will get annotated data with 100% accuracy in a timely manner. With over 5 years of experience in this industry, I understand the importance of quality and speed in annotations for ML.
I guarantee error-free annotations as for the algorithm to work effectively, it needs to be trained with a steady continuous influx of high-quality labeled data. The more accurate annotation is - the better algorithm performance will be. And less time, effort, and money you will need to spend on fixing poor annotations made by an inattentive and inaccurate annotator.

I had a great consultation call with Tetiana—she was knowledgeable and provided excellent strategies to improve my performance. She gave me a lot to think about and actionable insights to implement. Highly recommend her expertise!

Text Data Labeling/Annotator
Tetiana was able to deliver quality work on time. She was able to make suggestions and bring up issues in data that helped us build a quality dataset. Her communication over upwork messaging was clear and to the point.
She however was only able to work part time for us though we need her full time. She was already contracted with another business on upwork. We would have loved to have her *full availability*. We even communicated to her of our offer as we need someone senior to manage our annotation project in addition to individual contributions.

Job Success
Lviv, Ukraine - 5:55 am local time
With 8+ years in data annotation and 5+ years managing operations, I've built and trained annotation teams that consistently deliver quality while meeting aggressive deadlines. My specialty? Taking complex labeling requirements and creating clear, repeatable processes that anyone can follow.
What I Do Best:
Team Training & Quality Control
I develop annotation guidelines that actually work. From onboarding new annotators to refining workflows for experienced teams, I create training programs that reduce errors, speed up throughput, and maintain consistency across thousands of labels. I've trained teams of 20+ annotators across multiple languages and project types.
Multi-Modal Annotation Expertise
• Text: NER, sentiment analysis, intent classification, POS tagging
• Image/Video: Bounding boxes, polygons, semantic segmentation, 3D cuboids, keypoint annotation
• Audio: Transcription, speaker diarization, emotion tagging
Tools I Work With
LabelStudio, Labelbox, CVAT, Roboflow, Doccano, Amazon SageMaker Ground Truth, Supervisely -and I adapt quickly to proprietary platforms.
Project & Operations Management
As an Operations and Team Manger, I bridge the gap between technical requirements and team execution. I optimize workflows, manage budgets, coordinate with stakeholders, and ensure projects stay on track.
Why Clients Choose Me:
I don't just manage - I execute. I understand annotation at the ground level because I've done it myself for years. This means I can spot quality issues before they scale, troubleshoot labeling challenges in real-time, and train teams that don't need hand-holding.
