What I'm looking for

I seek a role combining research and AI/data annotation where I can apply academic rigor, ensure data quality, and grow with responsible technology projects.

I am an English Language and Literature scholar who applies linguistic training to data annotation, research, and academic writing. I combine scholarly rigor with practical experience in AI data work and freelance content production.

On Upwork I have maintained a five-star rating and a 95% job success score, delivering blogs, articles, transcriptions, and research writing with strict attention to quality and deadlines.

As a Data Annotator/QA Expert, I evaluated search results, categorized products, assessed AI-generated responses, and performed QA reviews to improve model performance and data integrity.

I seek roles that let me harness academic research strengths alongside modern technology—bridging communication, analysis, and responsible AI development to produce accurate, usable outcomes.
