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.
Story points, t-shirts, fruit salads, and now tokens. A messy, honest look at why estimation was already broken before AI showed up, and what it takes to keep planning sane when the tools move faster than the humans.
Anthropic's first harness article inspired ralphctl. Their second one on generator-evaluator loops pushed me to build an evaluator for v0.2.0, and the tool changed identity.
A hands-on walkthrough of RFC 8693 token exchange using Spring Cloud Gateway, Keycloak, and three frontend frameworks. Architecture, implementation, observability, and the things the docs don't tell you.
