Labeling Experience

Data Annotator

OtherVideoAction Recognition
As a Data Annotator at Hugo, I labeled large datasets to support machine learning model development. My work focused on marking and recognizing actions in recorded videos for human factors and ergonomics projects. I consistently performed quality control checks and error correction to ensure high-quality annotations. • Annotated recorded videos by marking sequences related to human actions • Adapted to diverse annotation tools and evolving project guidelines • Collaborated with team members to resolve annotation challenges • Ensured all outputs met accuracy and consistency standards

Personal ML Data Annotator (Projects)

TextClassification
I independently annotated and structured datasets for training small machine learning models in Python as part of personal projects. These projects involved text classification and tagging, as well as cleaning and validating data for consistency. I built scripts to identify duplicates, anomalies, and inconsistencies in datasets. • Labeled textual data for classification and tagging tasks • Implemented data-cleaning and validation scripts in Python • Ensured error-free and well-structured data for ML training • Managed personal projects involving iterative refinement of datasets
