Freelancer Overview

I am a detail-oriented Data Annotator with hands-on experience working on Meta-related projects through RWS, collaborating via vendor platforms such as Multimango and Parimango. In this role, I was responsible for annotating and reviewing large datasets across text, image, and multimedia formats, ensuring strict adherence to complex and evolving annotation guidelines. My work involved interpreting nuanced instructions, handling edge cases, and maintaining high levels of accuracy and consistency under tight deadlines. I developed strong analytical skills, enabling me to make sound judgment decisions while preserving data quality for machine learning and AI model training. I am experienced in meeting productivity and quality benchmarks, working independently in remote environments, and quickly adapting to new tools and workflows. My background in annotation, combined with my discipline and results-driven mindset, allows me to contribute effectively to high-performance data operations teams. I am eager to leverage my experience to support the development of reliable and scalable AI systems.
