I'm a Product Engineer & Technical Leader based in Berlin, Germany 🇩🇪
I enjoy building scalable products and distributed systems that solve real-world problems. My work sits at the intersection of engineering, architecture, and product, with a focus on turning complex challenges into simple, reliable solutions.
I'm passionate about designing high-throughput, low-latency APIs, event-driven architectures, and cloud-native platforms that scale with business needs.
Currently, I'm exploring AI-driven engineering workflows — combining LLMs, automation, and event-driven systems to make software development smarter, faster, and more efficient.
Previously, I've worked on large-scale replatforming initiatives, developer tooling, and cloud-native systems. I enjoy learning new technologies, sharing what I learn, and building products that make a meaningful impact.
