Hello, I'm
Based in Switzerland, I build software and write about what I learn along the way.
Selected topics I felt like sharing or talking about. Software, engineering, and whatever else catches my attention.
Personal projects I've been working on and like to show. Some useful, some just for fun.
Who I am, what I do, and how I got here.
Secure your Spring Boot app's messaging with OAuth2, not guest/guest. RabbitMQ joins your HTTP APIs' Spring Security setup as a resource server.
When I started ralphctl, 'harness' was a word from one Anthropic post. Now it's the third phase of AI engineering, there's an arXiv paper, and the whole field has standardized on the patterns I built early.
Agent harnesses orchestrate code generation. Delivery is a longer pipeline. Here's the mental model I've been using to plug team, tools, context, and models into one value stream, and where the agent harness fits inside it.
