Description

As a seasoned Data & Analytics leader with over a decade of experience, I help companies transform their data into growth. I’ve built and led high-impact analytics teams across fintech, e-commerce, and Web3, including roles at Zalando and P2P.org delivering data platforms, reporting ecosystems, and AI-driven insights that support strategic decisions and real-time operations.

I specialize in building end-to-end data infrastructures (dbt, BigQuery, Airflow), BI dashboards (Looker, Superset, Power BI), and data analytics / data science AI solutions that enable fast, confident decision-making and automation. I’ve helped scale startups, drive investor reporting, optimize validator performance, and launch client-facing data products—unlocking millions in added revenue and efficiency.

I’m now focused on supporting startups, scaleups, and product teams that want to operationalize data, boost performance, and build a modern analytics foundation. If you’re looking for someone who can translate business goals into measurable, data-backed outcomes, let’s talk.
