## About

```text
At Holland & Barrett, I use sales, inventory, and product performance data to support ordering decisions and improve stock management. I also review operational reports and KPIs related to sales, stock control, and store performance.

As a freelance dietitian and nutritionist, I collect and analyze client health, nutrition, and lifestyle data. I track progress and interpret findings to support personalized nutrition interventions and evaluate outcomes.

At Outlier AI, I evaluated AI-generated content against structured quality and accuracy criteria, identifying inconsistencies and factual errors. I documented evaluations and provided corrective feedback.

At Public Institute of Vocational Training (DIEK), I contributed to research activities for an EU-funded circular bioeconomy project, supporting information gathering, analysis, and reporting. I've also completed the Google Data Analytics Professional Certificate, developing practical skills in SQL, R, spreadsheets, and Tableau.
