Labeling Experience

Machine Learning Engineer Trainee (Data Annotation Focus)

OtherImageClassification
As a Machine Learning Engineer Trainee, I contributed to data annotation and labeling workflows for supervised learning projects. Responsibilities included labeling output data, validating model predictions, and improving data quality for ML pipelines. The experience took place in a structured training environment with hands-on practice. • Labeled and validated structured datasets for model training. • Practiced annotation-adjacent workflows and data quality control. • Utilized Python-based pipelines for data preprocessing. • Collaborated with a team to simulate real AI production environments.

Data Analytics Trainee (Annotation QA & Dataset Preparation)

OtherImageClassification
During my Data Analytics Trainee program, I prepared datasets for downstream modeling and focused on data quality assurance. Activities included identifying inconsistencies, normalizing data, and curating ground-truth data for supervised models. These actions supported annotation QA and reliable dataset construction. • Performed quality assurance on training data. • Curated and prepared datasets for supervised learning. • Cleaned, transformed, and validated structured data for annotation purposes. • Used Excel and SQL in the data preparation process.

I curated and annotated a custom training dataset for a real-time license plate detection and recognition project. My work involved applying bounding boxes to vehicle images and providing OCR ground-truth tags to support supervised model training. I iteratively refined the annotated data to account for different lighting and traffic scenarios. • Applied bounding box labeling to thousands of vehicle images. • Generated OCR ground-truth tags to enable license plate recognition. • Re-annotated misclassified samples based on model performance feedback. • Worked with Python, OpenCV, and TensorFlow in a computer vision context.
