What I'm looking for

I seek a data-focused role where I can apply annotation and visualization skills, collaborate cross-functionally, and contribute to model improvement and actionable insights.

I am an analytical data professional with hands-on experience in data annotation, analysis, and visualization, focused on improving AI model accuracy and delivering actionable insights. I leverage tools such as Excel, Power BI, Tableau, Label Studio, CVAT, and SageMaker Ground Truth to clean, annotate, and visualize complex datasets across text, image, audio, and video formats.

I have worked cross-functionally to ensure dataset quality and accessibility compliance, managed user support and feedback to optimize product experience, and built responsive web solutions using HTML, CSS, and JavaScript. I bring strong attention to detail, communication, and problem-solving skills to fast-paced, data-driven teams.
