Labeling Experience

Data Annotator & AI Training Specialist (Outlier.ai)

ImageImageBounding BoxBounding Box

Performed large-scale computer vision annotation including bounding boxes, instance segmentation, and keypoint labeling to support ML training pipelines. Validated and converted dataset files across JSON/CSV/XML formats, ensuring schema compliance for downstream model training. Applied ML-library-assisted data manipulation (NumPy/Pandas) within TensorFlow/PyTorch-backed workflows for consistent training inputs. • Annotated 50,000+ image/video samples for ML model training. • Maintained annotation quality scores consistently above 97% across 15+ concurrent projects. • Ran Python scripts to clean, validate, and batch-process annotation exports in JSON and CSV. • Supported RLHF rating/ranking of AI outputs to improve response quality and alignment.

OneForma

Data Annotation Specialist (OneForma/Centific)

OneFormaOneFormaImageImageObject DetectionObject Detection

Completed object detection (bounding boxes), human pose estimation (keypoints), and polygon segmentation annotations for computer vision datasets. Prepared and validated structured XML/JSON outputs to match client ML pipeline specifications for each annotation batch. Organized labeled outputs into consistent train/validation splits with aligned folder hierarchies and metadata records. • Used OpenCV to resize, normalize, and crop frames prior to annotation ingestion. • Transformed annotation logs using NumPy/Pandas into analysis-ready DataFrames for QA reporting. • Reduced annotation error rates by 22% across two project cycles via QA collaboration. • Produced schema-compliant annotation batches with consistent CSV/JSON metadata.

AI Data Contributor (Handshake AI)

TextText

Annotated NLP datasets for intent classification, named entity recognition (NER), and sentiment labeling to train downstream models. Converted raw collected data into ML-ready JSON/CSV using Python automation to eliminate repetitive formatting tasks. Enforced consistent field naming, null-value handling, and version-controlled JSON schema files to support reliable handoff to ML engineers. • Created structured intent/NER/sentiment labels for NLP model training. • Achieved quality scores above platform benchmarks while meeting daily throughput targets across multiple workstreams. • Reviewed TensorFlow/PyTorch model input specifications to ensure correctly shaped annotation outputs. • Contributed to a parallel image classification/tagging project for basic computer-vision labeling exposure.
