Freelancer Overview

I’m early in my data labeling and AI training data journey, with hands-on experience from coursework, online challenges, and a few small freelance projects in text classification, entity tagging, and image bounding boxes. I’m comfortable following detailed guidelines, asking clarifying questions, and maintaining consistency through checklists and spot checks. I use basic Python (pandas, regex) and spreadsheets for simple QC, and I’ve practiced setting up small gold sets and tracking agreement at a beginner level (percent agreement/Cohen’s kappa). I’ve dabbled with tools like Labelbox and Prodigy tutorials, and I’m quick to learn new platforms. What I bring is reliability, attention to detail, and a quality-first mindset. I document edge cases, propose guideline tweaks with examples, and iterate based on feedback. I’m familiar with privacy/PII basics, labeling for safety/toxicity, and simple active-learning loops (reviewing model-disagreement samples). I’m eager to support larger teams, take on repetitive tasks accurately, and grow into more advanced QA and guideline-authoring responsibilities as I build experience.
