About

Data Product Owner with a software engineering background, currently leading BI and data platform strategy at Mer Group.

I've grown from hands-on development into product ownership — which means I can talk credibly to engineers, architects, and business stakeholders in the same conversation.

Recent focus: unifying fragmented data platforms into Microsoft Fabric, establishing trusted KPIs, and protecting delivery timelines on mission-critical analytics.
