Experienced Data Annotation Specialist driving high-quality AI/ML datasets and workflow improvements.
What I'm looking for
I am a Data Annotation Specialist with over eight years of experience building, curating, and QAing datasets for conversational AI and other ML applications. I have influenced annotation taxonomy, refined workflows to improve throughput, and collaborated with data scientists to produce datasets that improved model performance and accuracy.
I deliver measurable results — from annotating and QAing over 500,000 conversational records to designing annotation tools and pipelines that reduced task time and retrieval latency. I mentor teams, lead guideline development, and apply Python, SQL, and NLP toolkits to ensure ethical, scalable data solutions across healthcare, customer support, and e-commerce domains.
