Dear Hiring Manager,

I am writing to apply for the Segmentation Annotator position. I hold a Ph.D. in Plant Sciences and have hands-on experience in biological image annotation, microscopy image segmentation, and high-quality dataset preparation for AI/ML applications.

Currently working as a Molecular Biologist, I bring strong domain expertise in cellular and molecular biology along with practical experience in annotating microscopy images using tools such as ImageJ/Fiji, CVAT, Labelbox, QuPath, and CellProfiler. I have performed precise segmentation of cells, nuclei, cytoplasm, tissues, and organelles using polygon, instance mask, and pixel-level annotation techniques, strictly following annotation guidelines and quality standards.

My background in molecular biology enables me to accurately interpret biological structures, reduce labeling ambiguity, and ensure biologically meaningful annotations. I am experienced in multi-stage quality control workflows (self-QC, peer-QC, auditor-QC) and in exporting ML-ready datasets in formats such as COCO JSON, PNG masks, CSV, and GFF. I also validate annotations using trusted biological databases including NCBI, Ensembl, UniProt, and Pfam.

In addition to manual annotation, I have experience supporting semi-automated segmentation pipelines in CellProfiler and performing image preprocessing tasks such as denoising, thresholding, and contrast normalization. I am detail-oriented, comfortable with repetitive precision work, and committed to maintaining high annotation accuracy across large datasets.

I am enthusiastic about contributing my biological expertise and annotation skills to support high-quality AI model training. I would welcome the opportunity to discuss how my experience aligns with your project requirements.

Thank you for your time and consideration.

Sincerely,
Dr. Babu Saheb Shaik
