What I'm looking for

I seek remote roles where I can drive model improvements through precise annotation, QA leadership, and collaboration with ML teams to scale high-quality datasets.

I am a Senior AI Data Annotation Specialist with over five years of remote experience supporting machine learning and AI systems across NLP, computer vision, speech recognition, and generative models.

I have led large-scale annotation projects including annotating and reviewing 100k+ text prompts and responses, improving model precision by 25%, and maintaining 98% QA accuracy on NLP projects. I collaborate closely with ML engineers to refine schemas, perform bias detection, and implement data validation workflows that raise model performance.

My approach combines careful attention to data quality, proficiency with common annotation tools and formats, and a commitment to scalable, auditable processes that support reliable model training and evaluation.
