About The Main Thread

The Main Thread documents how enterprise Java actually evolves.

It is not a news feed and not a framework showcase.
It is a growing map of patterns that help large systems change without breaking.

The focus is on:

• Quarkus and cloud-native Java

• Open standards and boring architecture choices

• AI systems built inside the JVM

• Developer experience as a design constraint

I write for people who design systems that must survive real production pressure.

About Me

I am Markus Eisele.

This publication is not an opinion outlet.
It is my working notebook for modern Java architecture.
