Freelancer Overview

I bring strong experience in AI training data through my roles as an AI Model Trainer at Outlier and as an AI Voice Recorder on Upwork, where I worked with structured guidelines to ensure high-quality datasets. My tasks included labeling, classification, data verification, and analyzing model outputs to provide targeted improvements. I consistently ensured accuracy, ethical standards, and workflow efficiency while collaborating with project coordinators. My recording work further strengthened my linguistic precision, consistency, and ability to follow technical requirements. Alongside hands-on training data experience, my certificates in AI for Business, Google Analytics, and negotiation complement my technical skills with analytical thinking and communication. Fluent in both Dutch and English, and known for discipline and problem-solving, I offer a strong combination of reliability, attention to detail, and the ability to contribute effectively to data-driven AI development.

In this project we were required to either write benign or harmful prompts in order to make the model fail its safety guidelines. We would engineer a prompt and the model would output two responses. We would then rate those responses on various dimensions.

In this project I was required to engineer prompts according to a set locale and topic. The model then would output 2 responses and I needed to rate those responses across multiple dimensions, such as 'instruction following', 'truthfulness', 'localization' and many more.
