Labeling Experience

Technical Product Delivery & Workflow Analyst – Data Annotation

Text
I evaluated qualitative user research and UX writing to translate unstructured feedback into structured, testable prototype parameters for engineering teams. My work included workflow analysis and establishing logic for administrative tracking and data management protocol improvements. This involved rigorous synthesis and annotation of user-generated text data for system enhancement. • Labeled and structured unstructured feedback into actionable engineering and testing parameters. • Conducted workflow and administrative data annotation for interface and portal optimization. • Applied internal/proprietary tools to facilitate annotation and data management logic structuring. • Supported cross-departmental prototype development through data-driven technical annotation.

Data Synthesis & Ground Truth Establishment Lead

Text
I led the evaluation and categorization of extensive user surveys, personas, and historical complaint datasets to establish baseline logic for platform redesigns. My responsibilities included synthesizing qualitative data and establishing ground truth standards for subsequent AI model logic. The goal was to convert highly unstructured user feedback into structured, high-fidelity outputs for platform improvement. • Performed data labeling by classifying, categorizing, and evaluating text-based survey and complaint datasets. • Ensured rigorous establishment of ground truth for supervised model training and validation. • Applied advanced qualitative data analysis to support platform redesign and feature benchmarking. • Leveraged internal/proprietary tooling for dataset organization and labeling consistency.

AI Prompt Engineer – RLHF for Model Evaluation

OtherTextRLHF
I contributed to AI research by supporting reinforcement learning from human feedback (RLHF) in advanced prompt engineering contexts for model evaluation. The work involved rating model outputs, fine-tuning prompts, and providing structured feedback to optimize AI agent workflow logic. This project enhanced the feedback loop between human evaluators and machine learning models for educational and healthcare platforms. • Participated in RLHF processes for AI-enabled platform development and logic improvement. • Labeled and analyzed prompt/response data to refine LLM-generated outputs and task workflows. • Utilized advanced LLMs (Claude, Gemini) and AI platforms (Cursor) as evaluation tools. • Supported experimental refinement and model retraining via structured qualitative feedback.
