Human. Technology Strategist. Bridge-Builder.
Hi, I’m Jonas Arnsmann – a passionate Enterprise Architect with a strong belief in the power of structured thinking, purposeful IT and pragmatic collaboration.
With over 15 years of experience in software engineering, integration, and enterprise architecture, I specialize in building scalable IT landscapes, reducing complexity, and aligning technology with real business impact.
Currently, I’m leading the development of an Enterprise Architecture Practice at STRÖER, one of Germany’s leading media and tech companies. My work focuses on enabling digital transformation through smart integration strategies, business capability modeling, and data-driven decision-making.
When I’m not shaping IT landscapes, I’m a husband, father of two, outdoor enthusiast, and photography lover. I believe in technology with a soul – and in organizations that combine structure with creativity.
