Labeling Experience

Senior AI Training Specialist (QA Lead)

CVATImageQuestion Answering

As a Senior AI Training Specialist (QA Lead), I led QA efforts for multimodal image question answering projects, ensuring high standards of alignment between images and textual responses. I performed meticulous audits of annotated datasets, focusing on grammar, clarity, and logical coherence in answers. I rigorously documented unanswerable prompts and maintained top throughput on complex items. • Ensured C2-level grammatical, punctual, and logical precision. • Drafted gold standard responses and objective rationales. • Specialized in edge case identification for ambiguous visual questions. • Maintained a 7–8 minute per item workflow for efficiency.

Video Annotation Specialist

CVATVideoTracking

As a Video Annotation Specialist, I handled high-precision multi-object tracking projects to support autonomous vehicle training. I managed object identity and permanence over sequences with significant occlusions and dynamic changes. I refined bounding boxes and collaborated with engineers to optimize taxonomies and reduce bias. • Handled annotation of 1,000+ video frames per project. • Applied frame-by-frame interpolation for precise object localization. • Coordinated with teams for taxonomy improvements. • Ensured accuracy at over 30 FPS using industry tools.

Data Labeler / Content Evaluator

Scale AITextRLHF

As a Data Labeler and Content Evaluator, I contributed to AI training by ranking and rating AI-generated text for quality and safety in RLHF projects. I performed precise OCR on low-quality images to enable document-processing AI models. I ensured compliance with strict safety guidelines by flagging inappropriate or sensitive content. • Evaluated and rated text responses for truthfulness and helpfulness. • Supported safety checks for content moderation. • Extracted data through OCR from challenging sources. • Worked across multiple platforms for large-scale labeling initiatives.
