In this workshop you’ll go beyond the basics and learn to diagnose and fix concurrency bottlenecks in production Kotlin systems — no lost jobs, no blocked threads. Using a forensic approach, we’ll investigate real performance problems hands-on and work through the tools and techniques needed to solve them with confidence.

What you’ll learn:

• How coroutines map to JVM threads (and where they beat traditional threads)
• Low-level mechanics: state machines, compiled output, CoroutineContext
• Forensic diagnostics: leak detection, Perfetto profiling, CI/CD regression testing
• Structured concurrency patterns: cancellation, supervision, exception handling

By the end of this workshop you’ll have the skills to track down and resolve concurrency issues in your own Kotlin codebase.

This workshop is for Kotlin engineers who know coroutine basics but are hitting real performance problems in production — and want to understand what’s actually going on under the hood.
