Summary
🤩
Rockstar🎓
Top SchoolLev Priima is a Senior Software Engineer in the San Francisco Bay Area with 11 years of experience building performant, production-ready systems across observability, JVM tooling, and cloud platforms. At Datadog he contributes to Java APM and OpenTelemetry instrumentation, improving agent stability, classloading performance, and testability for widely used observability tooling. His background spans low-level JVM and HotSpot work at Oracle through data engineering and search platforms as an engineering manager, giving him rare depth from embedded C/assembly to large-scale distributed systems. Comfortable leading both hands-on engineering and toolchain refactors, he brings a track record of pragmatic improvements (e.g., classloader caching and env/tag handling) that reduce runtime overhead and simplify diagnostics.

Role in this project:Back-end Developer
Back-end DeveloperContributions:6 comments in 1 day
Contributions summary:Lev primarily focused on improving the Datadog Java agent within the OpenTelemetry Java instrumentation project. Their contributions involved reducing the use of `Thread::setContextClassLoader` and optimizing class loading and caching mechanisms within the agent tooling. They also refactored the `ClassLoaderMatcher` to use Guava cache and other code improvements. These changes aimed to enhance performance and stability of the instrumentation agent.
