Freelancer Overview

While I have not worked in a dedicated data labelling role, my experience sits closely adjacent to AI training data work in several meaningful ways. In my Salesforce administration and consulting roles, I worked extensively with data validation, quality control, and the identification of inconsistent or inaccurate records, which mirrors the core function of data labelling and annotation work. I have a proven ability to review large volumes of information with accuracy, flag errors systematically, and maintain strict quality standards across structured workflows. My ISTQB Software Testing certification further demonstrates a formal understanding of quality assurance principles that translate directly into AI training data environments. What sets me apart is the combination of technical grounding and strong written English, which is particularly relevant for text-based annotation, prompt evaluation, and response rating tasks. I hold certifications in Claude AI Foundations and Claude for Nonprofits, and use Claude and Gemini as company-wide tools in my current role as a Solutions Engineering Intern. This gives me a practical, working understanding of how large language models behave, where they fall short, and what high-quality responses look like. This familiarity with AI outputs from a user and evaluator perspective is something I can bring directly to data labelling and AI training data work.
