Engineering Meetup in Prague: Beyond Thread Pools

### Curious about what Java 21 Virtual Threads actually change in real-world applications?

Join us for an evening of engineering discussions as Maxat Mansurov, Lead Java Developer at Tricentis, takes a practical deep dive into one of Java's most talked-about features.
Virtual threads are easy to start using, but understanding how they work—and when they actually improve performance—requires looking beneath the abstraction. In this session, we'll explore how virtual threads are implemented inside the JVM before diving into a real production case study from qTest.
You'll see how qTest's asynchronous background processing engine was redesigned using virtual threads, the challenges encountered, and the performance results that followed. Rather than hype, this talk focuses on the engineering trade-offs: where virtual threads shine, where they don't, and what you should consider before adopting them.

## Event Details

📅 Date: Tuesday, 12 August
🕕 Time: 6:00 PM
📍 Location: DOCK IN FIVE, Boudníkova 11, Prague, Czechia

### What you'll learn

• How Java virtual threads work inside the JVM
• The architecture of qTest's background queue and its scaling limitations
• Rebuilding part of the system using virtual threads
• Performance findings and practical lessons learned
• When virtual threads are the right tool—and when traditional approaches still make more sense

Whether you're passionate about Java internals, concurrency, the JVM, or simply enjoy understanding how systems work under the hood, this meetup is for you. It's also a great opportunity to connect with fellow engineers over food, drinks, and technical discussions.

## Speaker

Maxat Mansurov is a Lead Java Developer at Tricentis, working on the qTest platform. His work focuses primarily on backend engineering, with a particular interest in performance, concurrency, and understanding how software works beneath the abstractions: from the JVM and runtime to the engineering trade-offs behind modern systems. He enjoys sharing practical lessons from real production systems and learning from the engineering community.
