Eduarda Cezar

I’m an Analytical Professional and AI Data Specialist with 2.5+ years of experience in high-stakes international operations and technical document auditing. I combine linguistic precision with a STEM background to deliver high-quality data labeling and RLHF for AI training.

In my current role as a Data Research & AI Annotation Specialist, I execute high-precision 2D bounding box annotations, categorize complex data structures, and apply logical & temporal mapping to improve model accuracy. I’m also responsible for quality assurance & compliance, validating data against complex technical guidelines and maintaining throughput with Time Per Task (TPT) below benchmarks.

Previously, I supported regulatory documentation auditing and operational data integrity using a zero-error methodology across SAP and Orial systems. I also handled bilingual correspondence, reviewing technical certificates in English/Portuguese and coordinating international quotes—always prioritizing accuracy, cultural appropriateness, and data integrity in remote, fast-paced workflows.
