I built the distributed systems tools that AI coding agents keep getting wrong. As the maintainer of Spring Cloud Sleuth (now Micrometer Tracing) and Spring Cloud Contract, I designed the observability and contract testing frameworks used across the Java ecosystem. I'm a Java Champion and Senior Engineer at HeroDevs, and I previously worked on the Spring Framework and Micrometer teams at Pivotal (VMWare / Broadcom).

Now I use AI coding agents daily to build production systems - and I see firsthand where they fail. This workshop exists because I got tired of watching AI confidently generate code that ignores the hard problems I spent years solving: trace propagation, resilience patterns, service contracts, failure modes.

I don't teach from slides. I break things and help you fix them.
