What I'm looking for

I seek roles where I can apply data annotation and analysis skills to improve AI model performance, contribute to process improvements, work collaboratively in cross-functional teams, and grow into data or QA leadership opportunities.

I am a detail-oriented data annotation specialist with a Bachelor of Arts in Psychology from Lehman College and a diverse background spanning data annotation, inventory management, youth counseling, retail operations, customer service, and digital marketing. I have a strong record of managing large datasets, leading teams, and maintaining high accuracy—consistently delivering quality scores above 95% while improving workflow efficiency.

I leverage technical tools including SQL, Python, Tableau, Microsoft Office, Google Workspace, Adobe Creative Suite, and TELUS Ground Truth Studio to drive insights, optimize processes, and support AI model training. I am committed to collaboration, clear communication, and continuous improvement, and I bring practical experience in inventory control, mentorship, and marketing analytics to cross-functional teams.
