About this Gig

Need clean, accurate training data for your AI/ML model? I annotate, label, and QA-check your datasets so you get production-ready data, not just raw labels.


What I offer:

  • Image annotation: bounding boxes, polygons, classification
  • Video annotation and frame-by-frame tracking
  • Data labeling, tagging, and structuring (CSV, Excel, JSON, COCO, YOLO)
  • Built-in quality assurance on every batch, not an afterthought


Tools: CVAT, Labelbox, Google Sheets, Google Workspace


Why work with me:

Nearly 2 years leading data annotation teams of 30-50 people and training 300+ annotators. I don't just label data, I know how annotation projects break down at scale, and I catch errors before they reach you.


To get started, send me:

1. Sample images/data (5-10)

2. Your labeling guidelines or classes

3. Preferred output format


Let's build a clean dataset your model can actually learn from.
