LLM based code refactoring for large scale brown field code base
Yao Lu

This is a talk about how we refactor the code base and improve its observability posture for a system with 300+ git repos and 4GB+ of code and scripts. How we use the LLM to approach the problem, find the critical information, and create a migration plan and executed it.

I will share our learning and journey throughout this piece of work.

We would like to extend a special thanks to the Mantel Group for sponsoring the venue + drinks, and to Tim Baldwin of Sustain Recruitment for sponsoring the food.

This is a physical meetup!
Come along in person, or if you can't make it, we will also be streaming as usual to: https://www.twitch.tv/sydneyaltnet

Philip Laureano's talk on AI Memory.

Phil, a familiar face at Alt.Net, will be engineering a Napster clone from spec all the way to the client build using the same memory system between two different clients

We're excited to have Damian back again, this time to give a talk about a .NET message bus library.

-------------------------------------------------------------

Nimbus is an open-source .NET message bus library that's now over 13 years old. While the project hasn't had much public activity for a while, it's actually been quietly powering event-driven, distributed systems in production for years and processing millions and millions of transactions.
In this talk, we'll look the origins of the project. Why it was built, the problems it set out to solve, and how it has evolved.

Asynchronous messaging is at the core of what Nimbus does, and we'll explore why it's such a compelling pattern for modern distributed systems, and some of the scenarios and capabilities it has unlocked in real world systems.
We'll also cover what's new in the 2026 relaunch, including a live demo, and finish up with how you can start using it.

We have the usual 2 JetBrains licenses to give away at the end of the talk quiz.
