Senior Data Engineer — Berlin, Germany — 9+ years of engineering impact across media, e-commerce, pharma and tech.
// WHO I AM
I am a Senior Data Engineer with a passion for building things that scale. Over 9+ years I have designed, engineered, and delivered end-to-end data solutions that power the decisions of some of Europe's largest digital publishers, e-commerce disruptors, and global enterprises.
My journey started at Accenture in Bangalore where I built Data Warehouse systems for global pharmaceutical CRM rollouts. From there I moved through Cisco's automation products, an MSc at Jacobs University (Bremen), and a series of increasingly senior Data Engineering roles in Berlin's tech scene.
Today I lead data platform engineering at Bauer Xcel Media, where I am the first Senior Data Engineer in the German division — building the infrastructure that drives insights across 12 popular German digital publishing brands with 2 billion+ yearly pageviews.
