A Software Factory Build Report: What Worked, What Broke, What I'd Do Again

A Software Factory Build Report: What Worked, What Broke, What I'd Do Again
What happens when Java development stops being a sequence of human tasks and becomes an autonomous pipeline?

At Tessl, a software factory already merges more than 1,000 PRs a week. Agents raise issues, modify code, run tests, review changes, enforce quality gates, and merge work without a developer touching every step.

In this session, we’ll build the idea around a real Java application and trace an issue from specification to code, tests, review, and PR. We’ll look at deterministic gates, agent-driven Java code review, failure modes, trust boundaries, and the architecture required to keep autonomy from becoming chaos. We’ll also examine a bigger shift: when agents can write and review Java code, developers increasingly become the architects of the system that tells them what changes are allowed.

You’ll leave with a practical blueprint for building a Java software factory, plus the mistakes you’ll want to avoid.
