About us
The Atlanta Java Users Group (AJUG) is organized by Java Developers for Java Developers in order to:
Provide a forum for exchanging information and for brainstorming with other developers on how to successfully implement new Java solutions.
Deliver monthly technical presentations on the latest Java/JVM technologies.
Support the needs of both newbies and experts through related Study Groups targeted at Java Certification and Java-OO architectural issues.
Promote the advantages of Java as a development and deployment environment to the business and educational communities.
While our focus is around Java and the JVM, we also cover a wide variety of other related topics such as Agile development methodologies, mobile and client-side software development frameworks and tools.

How to join?
There are currently no dues or other formal requirements for joining AJUG. Simply join this Meetup group and start attending our meetings.
About Our Meetings
AJUG meets generally on the third Tuesday of each month from 7:00 pm to 9:00 pm in the Perimeter area:
Roam Interactive Workspaces
1155 Mount Vernon Highway, Atlanta, GA
Our meetings emphasize high-quality technical content and we encourage interaction among attendees.
From 5:30 pm to 7:00 pm, we usually have a pre-meeting hangout at a local Pub before the meeting starts officially at 7:00 PM:
the Royal Oak Pub next to the venue, so come early, hang out, have some food & drink, then head over to the venue for the main event!
Annual DevNexus Developer Conference
The Atlanta Java Users Group also organizes the annual DevNexus developer conference. For more information see: http://www.devnexus.com

Building a 4,000-Component Monorepo: How Spotify Uses AI to Scale Backend Dev
Roam, 1155 Mount Vernon Hwy NE #800, Atlanta, GA, USWe use the Luma site to host our events. SIGN UP HERE
Spotify's backend monorepo consolidates over 4,000 services, libraries, and components into a single repository built with Bazel, deployed to Kubernetes, and supported by 131 custom developer tools. This talk explains why Spotify chose a monorepo for its backend infrastructure, the tooling ecosystem that makes it practical — from the CLI wrapper and BuildBuddy remote execution to Declarative Infrastructure and automated monitoring — and how AI skills and agents have become essential to operating at this scale.
I will discuss the over 90 Claude Code skills that encode institutional knowledge into repeatable workflows, with a deep dive into /import-repo: a skill that has migrated thousands of polyrepos into the monorepo, evolved through 206 commits over 8 months, and taught us hard lessons about AI agent autonomy, context window limits, and the value of encoding failure patterns as guardrails.

Knowns and Unknowns: Testing AI-Generated Code

# Knowns and Unknowns: Testing AI-Generated Code
Let's face it, AI-assisted coding is rapidly becoming the primary way applications are being written. The power of writing a complex application or feature with just a few commands is too alluring to pass up.
But between the imprecise nature of language and LLMs' ability to "hallucinate", this creates many opportunities for bugs and unintended behavior to be introduced. Just telling an AI coding agent to "write tests" isn't enough to build confidence in an application's correctness, either.
In this presentation, we will review three distinct phases of testing AI-written code. The known knowns: using spec-driven development to define the business-meaningful behavior of your application. Known unknowns: using property-based testing to handle edge cases and avoid overfitting and unintended biases. And finally, unknown unknowns: using static analysis and mutation testing to avoid introducing bugs you didn't think about.AI-assisted coding is a rapidly evolving field, but this presentation should provide you with a framework and approach to build confidence when using AI to assist with writing applications.

Refactoring to Modernize Java Applications Using AI.
Roam, 1155 Mount Vernon Hwy NE #800, Atlanta, GA, US# Refactoring to Modernize Java Applications Using AI.
WE USE LUMA FOR REGISTRATION. SIGN UP HERE
IDEs have long provided ways to refactor code. Despite their effectiveness, that journey is arduous and time-consuming. Reluctance to refactor increases the cost of development. However, refactoring for its own sake can also lead to greater productivity losses. In this presentation, we will take a highly interactive approach. We will take an example codebase, identify modernization opportunities, use AI to refactor the code from a modernization perspective, and assess the tool's effectiveness and how we can guide it to achieve better quality and improved results.
