What I'm looking for

I seek roles focused on AI dataset preparation and annotation within collaborative teams that value accuracy, scalable workflows, and opportunities to grow technical skills.

I am a detail-oriented data annotation specialist with three years of hands-on experience preparing, labeling, and validating datasets for NLP, image, and tabular machine learning tasks. I focus on accuracy, quality assurance, and efficient processes to boost model performance.

I have supported AI model development across projects by collaborating with engineers, developing automated annotation workflows, and training new team members on annotation standards. I have also applied statistical analysis and risk assessment methods in finance settings, using tools such as Python, SAS, R, and advanced Excel.

I am committed to continuous professional growth in AI data preparation and seek opportunities where I can contribute precise dataset work, improve annotation pipelines, and support data-driven product development.
