Labeling Experience

Generative AI & NLP Instructor

Text
As a Generative AI & NLP Instructor, I created and delivered structured educational modules on prompt engineering and natural language processing for local tech hub members. I provided systematic feedback on student AI workflows, ensuring adherence to best practices in data input, output evaluation, and logical structuring. My role involved distilling complex AI concepts and guiding learners to improve their skills in AI model alignment and response evaluation. • Designed and delivered prompt engineering and NLP training modules. • Taught systematic approaches for AI-guided data labeling. • Reviewed and rated student-created AI prompts and outputs. • Ensured best practices in AI workflow design and quality assurance.

AI Data Evaluator & Annotation Specialist

Text
As an AI Data Evaluator & Annotation Specialist, I evaluated and annotated complex text and generative AI dataset outputs using strict predefined taxonomies. I analyzed AI responses, flagged inconsistencies, hallucinations, ambiguities, and logical errors, and directly contributed to improving next-generation AI models. I synthesized high-volume information to produce structured, reliable outputs and ensured data alignment through structured logic and critical reasoning. • Labeled and categorized text data and AI outputs following detailed rubrics. • Ensured quality and reliability by flagging errors in AI-generated content. • Worked remotely as an independent contractor with ongoing commitment. • Trained AI models for reliability across specialized subject matter.

Multi-Modal Image Annotation & Object Detection Optimization

ImageSegmentation
Performed high-precision data labeling for large-scale image datasets to improve the accuracy of object detection algorithms. Tasks included 2D/3D bounding boxes, semantic segmentation, and key-point annotation. Collaborated with ML engineers to identify and resolve edge-case misclassifications, resulting in a measurable increase in model confidence scores for autonomous navigation.
