About us
Jozi JVM User Group (Jozi-JUG)
Welcome to the Jozi JVM User Group! This is a community for anyone passionate about Java Virtual Machine (JVM) languages and related technologies. Whether you're a beginner, a seasoned developer, or somewhere in between, we’d love to have you join us. Our group hosts virtual and physical meetups, creating spaces for learning, sharing, and connection.
For Recruiters
We kindly ask that recruiters, staffing professionals, and headhunters respect this space as a sanctuary for developers. While we appreciate the work you do, Jozi-JUG is exclusively for those who code and create with Java and JVM technologies.
For Developers
Here’s how you can get involved:
- Attend our Meetups: Join us to learn, share, and connect with fellow JVM enthusiasts.
- Speak at a Meetup: Volunteer to share your knowledge by contacting the committee.
- Write for the Community: Contribute articles to our online platform to help grow and enrich the group.
Our Goals
- Foster the growth of the JVM community.
- Share knowledge and experiences to uplift one another.
- Build critical technical skills to support our country’s development.
- Create lasting friendships among Java developers.
- Have fun while learning and collaborating!

Talk: Concurrency Without the Complexity: Unleashing Virtual Threads (Project Loom) Part 2.Abstract:
Aphiwe Vuba will be demonstrating Bank4Z a full stack, secure banking platform she's building with Spring Boot, PostgreSQL, and Flutter.
Bank4Z demonstrates how modern Java virtual threads replace complex reactive code with clean, high-throughput synchronous architectures handling concurrent account lookups, JWT-secured transactions, and database operations at scale without exhausting platform thread pools.Speaker

Talk: Programming without syntax: The compiler is an LLMAbstract:
For decades, programming has meant translating ideas into syntax. But what happens when the compiler can understand intent directly?This talk explores an experimental framework where developers write .prompt files instead of .java files, allowing software to be built from natural language descriptions rather than hand-written code.
Through live demos, I'll show how the system works, the engineering challenges involved in making it reliable, and what this shift could mean for the future of software development.
Speaker
Aphiwe Viba is a software engineering student at WeThinkCode_ who loves using tech to solve real-world problems. She also serve as a Recruitment Ambassador, which lets her dive into community outreach and help mentor the next generation of developers.Lately, she's been channeling her focus into cybersecurity, learning how to bridge the gap between building cool digital innovations and making sure they are actually secure and resilient.
