Freelancer Overview

I have solid experience in data labeling, transcription, and annotation projects focused on improving AI training data. I’ve worked on diverse tasks such as tagging audio samples, reviewing linguistic data, and ensuring consistency across large datasets. My background in reviewing academic papers and thesis projects strengthened my attention to detail, accuracy, and quality control. I enjoy refining data so it’s clear, structured, and useful for model training, and I’m skilled at following detailed guidelines while maintaining efficiency and precision.

Labeling Experience

SFT Prompt–Response Writer & LLM QA

AppenTextPrompt Response Writing SFT

Worked on text-based SFT (Prompt + Response Writing) tasks, creating and refining prompts and writing high-quality model responses that follow strict guidelines. Produced instruction-following outputs with clear structure, correct tone, and consistent formatting (bullets, steps, concise explanations). Performed quality checks for: adherence to prompt intent, completeness, safety/PII compliance, neutrality, and language correctness (English/Spanish). Also handled light rewriting to improve clarity and reduce ambiguity, flagged failures (hallucinations, missing constraints, irrelevant answers), and documented brief justifications for corrections to meet QA standards.

Vehicle Image Annotation Specialist

TelusImageEntity Ner Classification

I worked on an image data labeling project focused on vehicles, where I performed entity (NER) classification using Telus tools. My tasks involved identifying, tagging, and categorizing different vehicle types, components, and attributes to support model training for recognition and detection systems. I ensured data accuracy through consistent quality checks and cross-validation with established labeling guidelines. The project required attention to visual details, adherence to labeling standards, and maintaining high precision to improve the AI model’s understanding of visual data.
