What I'm looking for

I’m looking to contribute to AI training and data labeling with strong quality control. I want to apply my data analytics skills to turn complex data into clear, data-driven decisions and continuous improvement.

I’m a data annotation and analysis specialist with hands-on experience labeling datasets for AI model training. I focus on maintaining high accuracy (95%+) through rigorous quality control, validation, and adherence to clear annotation guidelines.

In my current role as an AI Data Annotator / Data Labeling Specialist, I validate annotation quality across diverse dataset types, identify inconsistencies, and implement corrections to improve dataset reliability and model performance. I also collaborate with project teams on data quality initiatives, providing feedback that supports continuous improvement of labeling processes.

Alongside AI labeling, I’ve worked as a Freelance Data Analyst—collecting and interpreting complex client datasets, building PowerBI visualizations and interactive dashboards, and using statistical analysis to find trends, patterns, and correlations. Earlier, as a Quality Assurance Specialist, I developed standardized QA processes and quality metrics, supported 15+ team members with training, and used call data insights to improve operational performance and customer satisfaction.
