Elevated to Quality Reviewer role after demonstrating consistently high annotation accuracy on the Nidra WF9 AI image
training data project; audited and evaluated labeler submissions against defined quality benchmarks for a high-volume production

transformation instructions, and misplaced marking locations; issued structured rejection feedback with specific remediation
guidance for each failure type.

action-verb-led, specific, and free of technical jargon — ensuring data usability for AI model training.

background, lighting, and mood; applied a five-step priority scan methodology (Subject →Clothing →Objects →Background
→Style).
