What I'm looking for

I seek roles where I can lead and improve annotation workflows, mentor teams, and build high-quality ML datasets in collaborative, impact-driven environments.

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.
