I will do image annotation, segmentation, bounding box, text labelling and cvat for ml
AI Data Annotation, LLM Response Evaluation Specialist
About this Gig
Need clean, guideline-compliant data to train your computer vision model?
I provide manual, pixel-accurate data annotation and image labeling for AI and machine learning projects.
Services I offer:
2D Bounding Boxes: (YOLO, Pascal VOC)
Polygon Annotation
Image Classification
Object Detection Prep
Tools & Workflow:
I work primarily in CVAT (Computer Vision Annotation Tool), Roboflow, and client-provided annotation environments.
Quality Assurance & Verification:
Strict compliance with your custom annotation guidelines and edge-case rules
Two-stage verification: Manual inspection for tight boundary margins and zero label drift
Transparent communication on ambiguous or low-contrast targets
Deliverables:
Export-ready training datasets in YOLO (.txt), Pascal VOC (.xml), COCO (.json), or CSV format.
Message me to review your guidelines or request a 5-image pilot test!

FAQ
What annotation tools do you use?
I work primarily with CVAT (Computer Vision Annotation Tool) and Roboflow. If you have a proprietary or self-hosted annotation platform, I can also log in and annotate directly within your environment.
Can I test your quality before placing a large order?
Absolutely. You can message me anytime with your instructions and a sample of 3–5 images. I will annotate them for free so you can verify that my coordinate tightness and labeling guidelines match your model's standards.
Can you handle custom labels and complex polygon boundaries?
Yes. I annotate both regular 2D rectangular bounding boxes and multi-vertex polygon segmentation masks for complex, irregularly shaped objects.
Do you sign Non-Disclosure Agreements (NDAs)?
Yes. I treat all client data with complete confidentiality. I am happy to sign an NDA before you share your dataset, and your files will be permanently deleted from my local drive upon project approval.
What if I have a dataset larger than 1,000 images?
For high-volume projects, please contact me directly before ordering. I can provide a custom quote with a milestone delivery schedule and discounted bulk unit pricing.
