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

We are happy to announce that Simon Maple will be our special guest for this month's meeting.

What happens when Java development stops being a sequence of human tasks and becomes an autonomous pipeline?

At Tessl, we are a software factory that 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.
