Freelancer Overview

I have hands-on experience across multiple AI training and data labelling modalities, including text, code, vision, and audio. At Invisible Technologies, I worked as a senior contributor and Quality Analyst on AI training projects, reviewing and scoring AI-generated code in JavaScript and Python for correctness, logic, and adherence to coding standards. I also designed prompts and evaluation tasks to test model capabilities across vision and audio, identified failure modes, created annotated training examples to address them, and led training sessions for fellow contributors on efficient evaluation practices that measurably improved model accuracy and consistency across the team. At Turing, I currently lead quality assurance for a pod of 120+ AI trainers, where my pod has ranked number one for quality across the project, sustaining a score above 95%. I build and maintain performance dashboards to track trainer output at scale, design onboarding programmes for new members, and run retraining sessions for underperforming trainers, turning quality rubrics into actionable feedback. What sets me apart is the combination of hands-on evaluation experience across multiple modalities and the operational leadership to drive quality at scale, having both contributed to and managed AI training workflows at a senior level.
