From Context Engineering to Harness Engineering: Building Your Own Product Factory to Your Taste

I'm a software architect, tech lead, and product-minded engineer based in Switzerland, with over a decade of experience across startups and enterprise environments. At Raiffeisen Switzerland, I design and build financial market data and investment research platforms, focusing on distributed systems, event-driven architectures, and scalable backend solutions. My core stack includes Kotlin, Java, Spring Boot, TypeScript, Angular, and Kafka. I'm passionate about agentic AI, harness engineering, software factories, local LLMs, self-hosting, and game development. I enjoy challenging established practices, experimenting with new technologies, and building products from scratch. Outside technology, I'm a husband, father of two, and gamer pursuing financial independence (FIRE). This blog is where I share technical experiments, lessons learned, opinions, and unconventional ideas, without the corporate polish.
