I'm a product engineer and technical leader based in Berlin, Germany — passionate about building scalable systems, designing clean architectures, and turning ideas into impactful products.
I love working at the intersection of engineering, design, and business, where technology directly shapes user experience and product growth.
Currently, I'm tinkering with AI-driven workflows — exploring ways to combine LLMs, automation, and event-driven systems to make engineering processes smarter and faster.
In the past, I’ve worked on large-scale replatforming projects, developer tooling, and cloud-native systems.
I’m always learning, sharing, and building things that solve real problems elegantly.
