Freelancer Overview

I am a data labeler and AI evaluator with experience across text, safety, voice, and image classification. I have worked on structured evaluation projects such as Cyphers Evals, where I advanced to evaluator level and assessed prompt–response quality across accuracy, coherence, reasoning, and task completion. I also contributed to Red Pandas, focusing on safety evaluation and identifying harmful or biased outputs. My background in research, policy analysis, and complex stakeholder work in the mining and energy sectors strengthens my ability to follow detailed guidelines, apply consistent scoring frameworks, and work with high-volume datasets requiring precision and critical judgement. I complement this with experience in multimodal annotation from short-term image and audio labelling tasks with Aligner. This combination allows me to contribute both technical rigour and domain expertise to AI training workflows.

Labeling Experience

Voice and image data labeler – Aligner

LabelboxAudioClassificationEmotion Recognition

I worked on short-term multimodal annotation tasks for Aligner, labelling both voice and image datasets. Responsibilities included classifying audio clips by tone, clarity, emotion, and speaker characteristics, as well as categorising images by content, visual features, and required attributes. Work followed detailed guidelines ensuring consistency, quality, and accurate tagging across high-volume batches.

Cyphers Evals & Red Pandas – AI evaluator and data labeler

Internal Proprietary ToolingTextClassificationText Generation

I worked as an evaluator for Cyphers Evals and Red Pandas, reviewing and scoring large volumes of prompt–response pairs for accuracy, coherence, relevance, reasoning quality, adherence to instructions, and safety. Tasks included classifying model output by type, identifying harmful or biased content, applying structured scoring rubrics, and producing consistent evaluations across high-volume batches. I operated at evaluator level, contributing to quality assurance and guideline alignment.
