What I'm looking for

I want to build governed, self-service analytics platforms that translate complex data into clear executive decisions—pairing experimentation and predictive modeling with scalable dbt/SQL engineering to deliver measurable commercial outcomes.

I’m a Senior BI Analyst and Analytics Engineer with 9+ years of experience building scalable analytics platforms and data products that help product, commercial, and executive teams make confident, data-driven decisions. I specialize in analytics engineering, dbt, SQL, Python, experimentation, predictive modeling, and AI-powered analytics—always with strong data governance.

At Quandoo GmbH in Berlin, I’ve held dual ownership across analytics engineering and business analytics, powering commercial, product, and operational reporting with a trusted dbt transformation framework. I architected staging, intermediate, and mart models to establish a single source of truth for revenue, customer lifecycle, and commercial performance.

I focus on turning loosely defined business problems into executive-ready narratives and measurable outcomes—improving customer conversion by 12%, acquisition by 25%, revenue by 15%, and reducing churn by 20%. I also reduced cloud costs by 15%, cut deployment failures by 30%, and lowered ad-hoc requests by 25% by introducing an AI-powered analytics assistant on governed datasets.
