Labeling Experience

Biomedical Image & Biological Data Annotation

CVATTextEntity (NER) ClassificationSegmentation

Contributed to multiple biology-focused data labeling projects, including annotation of biomedical images, classification of cell structures, and tagging of genomic and ecological datasets. Ensured accuracy in identifying biological features such as tissues, cells, and organisms to support AI models in diagnostics and research. Worked on text-based biological datasets, performing entity recognition for gene sequences and protein interactions. Maintained high data quality standards by reviewing and validating annotations for consistency and scientific accuracy. This experience strengthened my ability to combine domain knowledge in biology with structured data labeling for AI and machine learning applications.
