High-quality AI training data can make or break your model. I help AI/ML teams scale data annotation with 95–99% accuracy, backed by structured QA workflows and reliable turnaround, across image, text, and audio datasets. If you're building computer vision or NLP models, I ensure your data is clean, consistent, and production-ready. 1. Experience handling large-scale datasets (10K to 1M+ annotations) 2. Multi-level QA pipelines (review, sampling, audits) 3. Expertise across CV, NLP, Geospatial, and ADAS use cases With 5+ years of experience in AI training data, I’ve consistently delivered high-accuracy datasets with fast turnaround and scalable workflows. I also provide access to multilingual annotation teams (German, Spanish, French, Portuguese, Japanese, etc.), enabling global dataset support. What I can help you with: • Image Annotation (Bounding Boxes, Segmentation, Tagging) • Text Annotation (Classification, Sentiment Analysis, NLP Tasks) • Audio Annotation (Event Labeling, Timestamping) • Data Validation & Quality Assurance I operate with a trained and scalable team of annotators, allowing me to handle both small pilot tasks and large-volume projects efficiently. Why clients choose to work with me: • 95–99% accuracy with strong QA systems • Structured workflows and clear communication • Ability to scale quickly based on project needs • On-time delivery with consistent quality I’m available to start immediately and open to both pilot tasks and long-term collaborations. I’m happy to start with a small sample or pilot task to demonstrate quality before scaling.
