Work History
AI Data & Annotation Lead
NordicTech Data Solutions
Copenhagen
08.2021 - Current
- Human-in-the-Loop Supervision: Curated, formulated and analysed more than 50,000 text and image datasets using Scale AI to train Customer facing Conversational Agents.
- Prompt Engineering and Response Evaluation: Implemented prompt engineering and assessed model-generated responses (ranking them in terms of accuracy, tone, and adherence to safety boundaries) using tools like Anthropic's Claude interface.
- Model Quality Assurance: Reduced biases and the 'hallucination' occurrence in enterprise level applications by collaborating closely with the engineering teams on the back-end, resulting in a 30% drop in end-user complaint tickets.
- Agile Coaching: Annotation data labeling training sessions were held every week and grading rubrics were developed to ensure a 98%+ consistency in data labelling tasks.

- Visual Data Classification: Recognized and labeled visual data inputs with Labelbox for autonomous research and tech apps with highly complex bounding boxes and polygons.
- NLP Processing: Linguistic data (Danish/English text structures) were cleaned and the semantic tagging was corrected.
- Pipeline Efficiency: Produced standard operating procedure (SOP) documentation that helped standardize the process for passing annotations to the deep-learning team, saving the developers 15 hours per month in manual data cleaning.
