PROFILE
Product Analyst with hands-on experience turning user and product data into decisions. I design and run A/B tests,
analyse user behaviour and pain points, form and test hypotheses, and turn results into clear conclusions and
recommendations that improve the product. I track key product metrics through dashboards, flag risks and trends,
and surface insights in reports and visualisations. I work with SQL and AI-assisted Python to prepare and validate
data, and bring AI/LLM automation experience that speeds up analysis and reporting.
